    Is there a way to do immutable backups with MSP360 Managed backup?

    Immutability / WORM support is coming - currently scheduled for August. I'll reply back with more details once I have them.

    Also very interested in immutable backups. Especially seeing other storage providers like Backblaze now support it.

    I would like to add my name to the list.

    The add-on question I have is, will the immutable backups be for other storage accounts like Amazon S3, Azure and Wasabi or just for MSP360 Wasabi accounts?

    The beta is now available for stand-alone customers and can be downloaded here. I don't have a date for Managed Backup yet.

    More information about the release is in this post:

    Any update on this?

    It's available for stand-alone users in the 7.2 agent release. It's also available, by request, for Managed Backup users with Windows agent version 7.2+. Please contact Support to request the feature be enabled if you want to play with it from the agent-side. It's not yet configurable from the management console. We are planning to officially release mid-October. You can read more about the feature as implemented for stand-alone users here: https://help.msp360.com/cloudberry-backup/backup/about-backups/gfs/immutability

    It seems that it only the GFS full backups are made immutable. Is there any way to apply this to the incremental backups based on a given full backup?
  • David Gugick

    That's true. But the full backups are synthetic fullls using all the bits and bytes already in the cloud to create the next set. So if you create a full backup every week then you'll have a new immutable backup weekly. Does that help? If not please describe your retention settings and a little more detail and maybe I can offer an alternative solution.

    I was looking at Arq and how they handled this, just as a reference. If I'm reading this correctly, they set the object lock time period to be the sum of the specified "keeping" time for the backup plus the interval between full backups or their equivalent "refresh", if I understand correctly (not certain I do perfectly). Anyway, the proposal I'd make is that you set the object lock time period to be the sum of the keeping time and the interval between equivalent backups, and for each incremental you set the object lock time to basically the keeping time for the relevant full backup plus the time to the next full backup. That way all files in the full+incremental are kept for the GFS keeping time, at least and any incremental backup is available. If one is trying to protect against ransomware by having backups, this just protects the files created between full backups. I kind assume in the ransomware case that the last backups are suspicious and I will need to go back to a restore point that precedes the attack. Protecting the incrementals with immutability means I can pick a restore point that is closer to the time of attack and rescue more files.

    I haven't set up real backups with the new backup format yet. I'm not 100% clear that you recommend switching to it now. That is, is the feature fully ironed out. I know it is just off beta, was beta until fairly recently.

    Given that each full backup is adds a substantial amount to my storage, I haven't settled on the right compromise between having a lot of GFS full backups to restore to and the extra storage for that. I might think that doing only say annual full backups and having incrementals provide the restore points across the year with a keeping period of just under a year would be a good solution where the backup storage would only be about twice my dataset size plus some for all the incrementals. Perhaps you might suggest weekly full backups with keeping period of say 2 weeks. I don't really know. My point is that not protecting the incrementals with immutability seems to make the feature less complete.

    Here's my proposal for immutable. You know the time to purge for each full backup (it shows in the storage view), so when you do an incremental backup on top of that full backup, set the immutable time on the incremental to the time to purge of the underlying full backup.
