Backup error: The archive is invalid or its type is unsupported
Hello,
Many computers in my vault encounter error during backuping: The archive is invalid or its type is unsupported.
I read that the problem may be caused be corrupted chain of inceremental archives. But it happens also when i force to full backup. I have also followed this kb: kb. acronis. com/ content/ 60129.
1 month ago I migrated management server to another machines and plugged again existing storage nodes. During this occasion I recreated backup plans. Maybe it can interfer with archves created in old plans?
I attached screenshot and logs of one, representive machines. The problem occurs on many other also.

Hi Peter,
No, the kb doesn't solve problem. I didn't migrate to new version. Just created new plans. But on backups i have new entries for some computer, other are still using the same.

Hello Oskar,
sorry to know that moving your Storage Nodes and Management Server did not go flawlessly.
I recommend that you try to re-add the vault and rescan it. It can be done the following way:
- detach the vault (open Backups -> Locations and use "x" to remove the vault. The data should not be deleted)
- after the vault is removed the fdb database with vault ID should be created in the vault folder (like 6C04472B-1DB9-4471-A663-F3296F1469AF.fdb)
- please move this fdb file from this folder (when the fdb file is missed the software will rescan the vault after it is added);
- please add the vault back (Backups -> Locations -> Add Location, then please choose Acronis Storage Node and specify the path to vault folder);
- after the vault is added (it can take time to analyze the vault content), please check that the archives are available
- try to back up again.

Hello Oskar!
My only tip is the "solution" I did in a similar situation, that involved deleting all archives of the machines that failed this way. I however didn't mind losing previous backups, since they haven't been properly configured for years anyway.
If you do mind, at this point I suggest you Contact support. Please share the outcome either way!

Hello Oskar.
The worst scenario is that your backups could be corrupted. If backup validation reveals it, then re-creating backups could be an option.
I recommend you following instructions from this KB article: https://kb.acronis.com/content/63066

OK, I will try to remove damaged backup.
Usually I have a trouble to find correct backup files in vault. Could you advice me how to smoothly find correct file to remove?
Regards,
Oskar

Hello Oskar!
I find it's fastest when you look for the arl in the log. It's structure is like this:
[storagenodeGUID]/[locationGUID]/[archiveGUID]
In your shared activity log:
'arl:/1AD3FE1C-F7CB-4C66-A07E-3F4822A136F6/6C04472B-1DB9-4471-A663-F3296F1469AF/BE1FDCC0-D844-44C5-A3CB-A14B69B728B6'
- storagenode = 1AD3FE1C-F7CB-4C66-A07E-3F4822A136F6
- location = 6C04472B-1DB9-4471-A663-F3296F1469AF
- archive = BE1FDCC0-D844-44C5-A3CB-A14B69B728B6
Then search the archives table of the acronis_vault_manager DB, where the ID is the archiveGUID. You'll find the name of this archive as it appears in the backups view on the management console in the name field.
You can double check on the management console that you are looking at the right archive in Location>Backups>Select a backup>Details>All properties>id
If you need to find an archive on the file level for some reason this is the structure of the computers folder:
[agentID].[resourceID]\users\[security ID]\archives\[archive ids]
A simple search started on the computers directory with the archive id will find a single result.

I performed these steps, but result is still the same - unsupported or invalidarchive.
1. Unplug vault
2. Remove all backups regarding to the agent
3. Create and assign new backup plan
4. Connect location again
5. Ensure there aren't any archives regarding problematic computer
6. Manually run full backup
Does anyone has an idea? Maybe I should try to create another vault/location?

Hello Oskar.
I have reviewed your activity log and noticed that the Acronis Cyber Backup 12.5 Agent that is used to back up is 14300 build (the latest one) but Acronis Storage Node is 11010 build. The root cause can be in different versions. Please update Acronis Storage Node to the latest build (possible server reboot will be required) and try to back up again.
If the problem still there, then we need to ask for additional information for further investigation:
- please create a new backup plan and reproduce the problem (so new archive should be affected);
- then please collect Acronis System Information from the Acronis Storage Node server and from the PC that you are trying to back up (2 reports);
- please upload these reports to the FTP link that I've sent you in a Private Message.
I also strongly recommend that you open a case with Acronis Support Team on this issue.

Dear Maria,
Yes, it was the problem. But updating agent was not enought. I had to remove archive, then update agent and create a new one. Now it's working!
Very thank you!
