Comet 24.11.0 Dione​

Comet 24.11.0 Dione, our latest Quarterly release, brings 11 new features and 16 enhancements, including Disk Image for Linux, restoring Disk Image backups to Hyper-V VHDX file format, bulk action improvements and more.

The full set of changes can be found in the release notes.

Why Dione?​

This Quarterly release is named after Saturn's moon Dione. Fun fact: This moon hides a cool secret. Underneath its thick, frozen crust, scientists believe Dione harbors a subsurface ocean, much like its famous neighbor Enceladus. This hidden ocean makes Dione a surprising contender in the search for extraterrestrial life.

Webinar announcement​

Join us for our Quarterly webinar on Tuesday 10 December (3pm EST / 12pm PST)](https://app.livestorm.co/comet-backup/quarterly-releases)! Comet's CTO, Mason and Product Engineering Manager, Callum will cover all the latest product updates, with a live question-and-answer session at the end.

New Feature: Linux Disk Image​

Your input is an important part of what we decide to build at Comet. Disk Image for Linux was a highly upvoted request in our Feature Voting system, so we're excited to share this new backup type with the Comet community.

Linux Disk Image allows you to protect your Linux computers and servers. If your endpoint goes down (with ransomware, hardware failure or human error), having a Disk Image backup allow you to restore to a previous state on a new machine, eliminating the hassle of reinstalling and configuring devices from scratch when a disaster occurs.

Key Features​

• Bare-Metal Backup: Protect entire disks and partitions for full system recovery.
• Restore Anywhere: Bring your system back to life on physical hardware, virtual machines or even the cloud.
• Granular Restore: Quickly restore files and/or folders from the backup when key files need to be recovered.

When setting up Linux Disk Image, you are able to choose what disks and/or partitions you want to protect. Once you've selected what you'd like to protect, all of the data is deduplicated, compressed, and encrypted as it is backed up on the fly. This means all of your data is secure as it is uploaded and less storage space is used to store the backup.

You are able to restore a Disk Image backup to physical hardware, a Hyper-V VM or a VMware VM. Comet's flexible Disk Image recovery options give you full control over how the Linux endpoint is restored.

If you'd like more information about Linux Disk Image, check out our blog post here

Linux Disk Image is available in Comet 24.9.8 or later.

New Feature: Restore Disk Image To Hyper-V​

When restoring a Disk Image backup (for both Windows and Linux), there is a new option to restore the data in Hyper-V VHDX file format, which eliminates the need to manually convert our Disk Image virtual disk files into a format Hyper-V will boot from. This is a great improvement to our Disk Image recovery environment as you can restore backed up devices to Hyper-V even faster.

The conversion happens on-the-fly as part of the restore process. The resulting file can be used immediately in Hyper-V, or uploaded to Microsoft Azure to boot in a cloud virtual machine allowing you to restore any Disk Image backup quickly.

This joins our existing support for restoring Disk Image backups to VMware ESXi-compatible files.

New Feature: Bulk Assign User Policies​

User Policies are a great way to restrict what a user can and can't do. For example, you can prevent new Protected Items from being created, or ensure the main disk drive on everyone's laptop is always protected.

We've extended the "Bulk Actions" button on the Users page to support assigning user policies in bulk. This is great for organisations that require the same rules to be applied to a large number of users.

Comet-Hosted: Now Available In Australia​

We are pleased to announce that Comet-Hosted is now available to be hosted in Australia. Comet admin now have the choice of five geographically diverse locations to choose from when selecting where their Comet-Hosted server should be located.

New Feature: Hyper-V and VMware Quotas​

Comet works with a wide range of service providers, from highly managed to low-touch, and everywhere in-between. If you are a service provider who offers the software directly, you may be want to restrict your customer from backing up additional virtual machines. To support this, we have added a quota feature for the number of Virtual Machines:

Adding this quota limit to your customer accounts will ensure that as a service provider, you are in control of how many Virtual Machines your customers are allowed to backup.

Self-Hosted Management Console Admin Account Setup Redesigned​

When setting up a Self-Hosted Management Console for the first time, customers will now be asked to configure the default admin account details in the setup wizard or when first opening the web interface. This redesign encourages first time Comet admins to configure memorable admin account login details.

Comet 24.8.0 Tethys​

We're very pleased to announce our latest Quarterly release series - Comet 24.8 Tethys. This is the the latest entry in our quarterly rollup series, that branches off from our main rolling Voyager development into a fixed target for you to qualify and build your service offering upon.

Tethys is a moon of Saturn and is named after the Titan from Greek mythology. The best photos and scientific data about Tethys come from the 2015 visit by the Cassini spacecraft, named after Giovanni Cassini who discovered Tethys in the 1680s. Tethys was thought to be the closest moon to Saturn for 100 years, until Mimas and Enceladus were discovered in the 1780s, pushing Tethys out to third place. Tethys' orbit is still close enough to Saturn that it passes right through Saturn's magnetosphere. On Earth this would make for a dazzling aurora, but Saturn's auroras are only visible in UV light.

Tethys is a lot smaller than our own moon, at only 1% of the mass, and it seems to be almost entirely made of water ice. The nearby moon Enceladus has geysers that spray ice out into space, and this tends to create a thin ring around Saturn of ice particles. Tethys orbits right through this area and is sandblasted by these ice particles, making Tethys extremely shiny and and reflective.

As for the software, Comet 24.8.0 Tethys brings 7 new features and 25 enhancements, including support for advanced Windows metadata; granular restore from Linux filesystems; additional retry features; the ability to bulk convert from Storage Role to direct-to-cloud storage; and much more.

The full set of changes can be found in the release notes.

Webinar announcement​

If you'd prefer to watch rather than read, we're hosting a webinar to discuss this new quarterly release and all the new changes. Please register before we go live on Tuesday 10 September (4pm EDT / 1pm PDT) to catch up on all the latest Comet news with Comet's CTO, Mason and Product Engineering Manager, Callum. As usual, there will be time for a live question-and-answer session at the end of the presentation.

As well as that, we have many more videos available on our website, including guides on getting started with Comet, individual features, demonstrations with our technology partners, and webinars for previous quarterly software releases.

Configurable Retries For Failed Backup Jobs​

When a backup fails, it can lead to manual interventions or escalations to your technical team. Both of these are time consuming and frustrating when they occur. To prevent this, Comet retries 1000s of times during a backup to make sure it succeeds. Comet does this by retrying S3 APIs to make sure uploads and downloads succeed, as well as retrying any network errors that we determine as retryable.

Even though Comet has 1000s of retries within a backup, errors that can cause a backup to fail are inevitable. This can be from many various and often external factors such as service disruptions or hardware failures. When a backup fails due to these errors, often restarting the backup will succeed.

Our new Configurable Retries feature allows you to configure how many times a backup should attempt to retry when an error occurs, and how long it should wait to retry the job again. When this feature is configured, Comet will not mark a backup job as failed if it going to retry again later. Instead it will be marked as "Running (retry)" so you are able to see that Comet is still trying to get a successful backup.

It is important to note, that when Comet retries a job using this feature it needs to rescan all of the data in the Protected Item again. This is because it starts the job again from scratch. This does not mean all of your data will be uploaded again as Comet makes use of client-side deduplication and compression. This means that only the changes that weren't uploaded in previous attempts will be uploaded to the Storage Vault.

You can configure the new retry feature in two different ways. The first is by policy. You are able to configure per policy how long Comet should wait after a bacukup job fails, as well as how many times Comet will retry a failing backup job before it reports the error status. When a user has this policy applied, all Protected Items configured for this user will have the new retry feature applied.

You can also configure this feature per Protected Item. This provides you with a lot of flexibility as you can select Protected Items you would like to retry, rather than applying it to all Protected Items configured for a user.

To do this, you will see a new option on the Protected Item Schedule

Overall, this is a great new addition to Comet as it allows our MSPs to have Protected Items dynamically retry when an error occurs. This will help reduce the number of escalations to technical teams for intermittent issues.

Restore Windows Disk Image Backups From Linux​

In Comet 24.8 Tethys, Comet users will be able to restore Windows Disk Image backups directly from a Linux device. This makes cross-platform data recovery a lot easier as you no longer need a Windows device to restore Windows Disk Image backups.

To restore Windows Disk Image backups from Linux, you can use the Comet Backup desktop app or the Comet Server web interface. Because the Disk Image backup will have been performed by another device, you will need to login to the Linux device using the same username and password as the Windows device. This will allow you to restore Protected Items from other devices. The examples below are from the Comet Backup desktop app running on Ubuntu.

Once you have selected the Windows Disk Image Protected Item you would like to restore from you have four different methods to recover the files. These are restore to physical device(s), restore as virtual disk files, granular restore and restore as VMware virtual disks.

Restoring to physical device(s) allows you to write the data directly to a physical or virtual drive that is connected to the Linux device. You can then use the drive to boot the restored Windows device.

Restoring as virtual disk files allows you to create a VMDK file that contains all of the restored data. You can then load the VMDK into your preferred hypervisor such as VMware ESXi to boot the restored Windows device.

Granular restore allows you to recover a selection of Files and Folders without having to restore or boot the whole disk. This is great if you just need to grab a couple of important files quickly without having to restore the entire Windows device.

Restoring as a VMware virtual disk is similar to our virtual disk restore mode, except it converts the VMDK into a format that is bootable by VMware without any other steps required.

Each of these options provide you with flexibility to recover data from our Windows Disk Image Protected Item, whether it's the entire device, or just a couple of urgent files you need to grab.

Linux Based USB Recovery Media For Windows Disk Image Backups​

We are excited to introduce a new Linux based recovery media to restore Windows Disk Image Protected Items. Prior to Comet 24.8 Tethys, creating USB recovery media relied heavily relied on Windows to create a small ISO with Comet pre-installed to restore Disk Image backups.

The Windows based recovery environments relied on WinRE (Windows Recovery Environment) or Windows To Go to be installed on the device creating the recovery media. This meant for distributions of Windows where WinRE or Windows To Go is not available, it is not possible to create USB recovery media for Comet.

In Comet 24.8 Tethys, you will now be able to create a Linux based recovery environment. The process uses Docker to create a Debian based ISO with Comet pre-installed. This works well with our new Windows Disk Image backup restore capabilities from Linux announced above.

To create a Linux based recovery image, click "Create Recovery Media" on the Comet Backup desktop app. If the device also has Docker installed, you will see the new Linux ISO option becomes available.

Once the recovery image has been created, simply image it to a USB device. You will then be able to select it as a bootable device.

Once the recovery media has booted on the device, you will automatically be logged in and shown the pre-installed Comet Backup desktop app.

Automatic Storage Vault Locking Cleanup​

Sharing a Storage Vault is a fantastic way to reduce storage costs as Comet is able to deduplicate data across all devices that share a vault. This means, we only need to store one copy of the same file that exists on all devices. To ensure data is safe at all times, Comet uses Storage Vault locking to ensure one device doesn't remove essential data that another device was using.

If a PC shuts down unexpectedly such as if a laptop runs out of battery, Comet may leave a Storage Vault locked. This prevents other Comet devices that share the same vault from working, as when a Storage Vault is locked it means a device is running a data sensitive operation. One such operation is a retention pass.

Comet attempts to clean up Storage Vault locks, but this only happens when a new backup job runs. To improve how frequent backup jobs fail due to Storage Vaults being locked, Comet will now automatically remove vault locks when a devices wakes from sleep or when it boots.

This is a great improvement for our customers who have multiple devices sharing the same Storage Vault.

Comet 24.5.0 Enceladus​

We're very pleased to announce our latest Quarterly release series - Comet 24.5 Enceladus. This is the the latest entry in our quarterly rollup series, that branches off from our main rolling Voyager development into a fixed target for you to qualify and build your service offering upon.

Enceladus is a moon of Saturn and is named after the giant Enceladus of Greek mythology. There are a few worlds that are thought to have liquid water oceans beneath their frozen shell, but Enceladus sprays its ocean out into space where spacecraft can sample it. From these samples, scientists have determined that Enceladus has most of the chemical ingredients needed for life, and likely has hydrothermal vents releasing hot, mineral-rich water into its ocean. Enceladus is about as wide as Arizona, and it also has the most reflective surface in our solar system. Because it reflects so much sunlight, the surface temperature is extremely cold, about minus 330 degrees Fahrenheit (minus 201 degrees Celsius).

For users coming from the previous 24.2 Mimas quarterly release series, Enceladus adds 6 new features and 38 enhancements. Some of the new features we are excited about are:

• Hyper-V Changed Block Tracking (CBT) support
• Impossible Cloud Storage Templates
• SMB Storage Vaults
• Comet Backup desktop app Protected Item wizard refresh
• Syncro integration
• Server Self Backup enabled by default

The full set of changes can be found in the release notes.

Microsoft Office 365 Protected Item Performance Improvements​

Over this month, we have made significant improvements to the backup performance of our Microsoft Office 365 Protected Item. These performance improvements mean the backup job completes faster, as well as reduces the amount of data we need to upload. We expect partners to see Microsoft Office 365 Protected Items finish up to 30 times faster.

Disk Image Drive Letter Selection​

When configuring a Disk Image Protected Item in the Comet Server web interface, it can be difficult to configure when the device is not currently connected to the Comet Server. To help partners configure a Disk Image Protected Item more easily, we have added a new option to select disks to protect by drive letter.

Bulk Upgrade CPU Limits​

Our Bulk Upgrade feature is a great way to keep Comet Backup desktop app installs up to date with the latest version that the Comet Server is running. However, for Comet Servers with many tenants using custom branding, a Bulk Upgrade campaign to upgrade older clients consumed significant CPU time building new client installers quickly.

In Comet 24.3.8 we added a new configuration option to limit the maximum number of CPU cores Comet can use during a Bulk Upgrade campaign. This is a fantastic improvement as it reduces the burden on system resources during a Comet Server upgrade. It also provides a more robust Bulk Upgrade campaign, as Comet Backup desktop app installs can be upgraded without overwhelming the Comet Server's resources. For more information, you can check out our documentation here.

Windows System Backup Protected Item - Deprecation Notice​

Our Windows System Backup Protected Item is being deprecated. Before we added our Disk Image Protected Item, Windows System Backup Protected Item was a great way to backup and restore entire Windows disks. However, it required spool space (temporary storage) to be able to perform this backup. This means for a 500GB disk, Comet requires an additional 500GB of free space for this Protected Item to work.

Because of this limitation, and how difficult it is to setup, we have always recommended partners use our Disk Image Protected Item. To assist partners through this change, we have built a Windows System Backup to Disk Image conversion tool. For more information, you can see our documentation on the tool here.

We will be removing this Protected Item in November (Comet Release 24.11).

This article covers what's new our latest Quarterly release series from December 2023 to February 2024. Read the release notes here.

Comet 24.2.0 Mimas​

We're very pleased to announce our latest Quarterly release series - Comet 24.2 Mimas. This is the the latest entry in our quarterly rollup series, that branches off from our main rolling Voyager development into a fixed target for you to qualify and build your service offering upon.

Mimas is named after a moon of Saturn, which in turn takes its name from an ancient Greek mythological giant. Mimas is relatively small compared to Earth's moon, with a diameter of about 396 kilometers (246 miles). Its composition is primarily made up of water ice with a small amount of rocky material. Its most distinguishing feature is a giant impact crater which stretches a third of the way across the face of the moon, making it look like the Death Star from "Star Wars."

For users coming from the previous 23.11 Saturn quarterly release series, Mimas adds 3 features and 15 enhancements, including Dark Mode for the Comet Server web interface and a Debian installer for the Comet Backup desktop app as mentioned below.

The full set of changes can be found in the release notes.

Dark Mode for the Comet Server​

To continue our visual improvements to the Comet Server web interface we have added Dark Mode support. This completely overhauls the look and feel of the Comet Server and automatically applies based on the theme you have chosen for your system. Next time you have a chance check it out by logging into your Comet Server and clicking the new toggle button in the top right corner.

Light Mode:

Debian Installer for the Comet Backup desktop app​

To make it easier to install Comet on your Debian Linux installs, we are pleased to announce our new Debian Installer. Our new installer will walk you through all of the required steps to install Comet. Comet is installed as a systemd service meaning it will now automatically start when your device boots.

Once installed you can still upgrade Comet remotely using the Comet Server web interface meaning you now have multiple options for managing, installing and upgrading Comet on your Linux devices.

Improved S3-compatible Object Lock Performance​

Object Lock is a great way to add additional security to your data stored in an S3-compatible Storage Vault. This month we've been hard at work finding ways to optimize Comet's performance when backing up to an S3-compatible Storage Vaults. We have found a way to significantly decrease the time taken to extend the object lock duration on objects stored in the vault. As a result, backup jobs to an S3-compatible Storage Vault now complete up to 16 times faster than before.

Custom Headers added for Custom Remote Buckets​

Comet has a great list of S3-compatible storage providers that we have storage templates for. To add better support for other S3-compatible storage providers you can now add Customer Headers to a Custom Remote Bucket in the Comet Server web interface. This greatly expands your options for which provider you would like to use as you can now add additional data such as long lived authentication tokens as part of the request Comet makes when connecting to the storage provider.

Faster Logins between the Comet Account Portal and Comet Hosted​

Once Comet Hosted is running our new 24.2.0 Mimas release, we will enable the overhauled login button for Comet Hosted servers from the Comet Account Portal.

The new login button shares credentials between the Comet Account Portal and Comet Hosted meaning you no longer need to remember two sets of passwords. Because of this we have been able to solve all of the failing cases and can provide you with a reliable login experience for your Comet Hosted servers.

Once you've logged in with the new system for the first time, when you log out of your Comet Hosted Server you will see a new Login with Comet Account Portal appear on the login page. This allows you to jump straight back into your Comet Hosted server faster than ever before. This button will only appear on web browser sessions that remember you've clicked the login button from the Comet Account Portal first to ensure we don't show Comet branding to unexpected users of your Comet Hosted Servers.

VM Pricing Adjustments​

At Comet, we are committed to continuously improving our products and services to meet your evolving data protection needs. In order to do this, occasionally we find it necessary to make adjustments to our product offerings. We are updating our pricing structure in order to further standardize our virtual machine protected item types – VMware and Hyper-V.

Effective February 28th 2024, we are introducing a new unlimited guest license option for VMware, priced at $39. If you have 8 or more VMware guests backing up, you will automatically get the unlimited pricing; no action needed on your part. This change supports your business growth as you scale and add VM deployments.

Also as of February 28th 2024, we are dropping the $2 base charge for Hyper-V. You will only pay the booster charge for all virtual environment backups (both VMware and Hyper-V) going forward.

To bring our virtual machine licensing into alignment, starting February 28th 2024, Hyper-V licensing will be charged at $3 per guest or $24 for unlimited guests per host.
