Recovering disks and volumes by using bootable media - all backups must be present
Hi, sorry for my English, it is not very good.
I am in charge of some support tasks for a client, which includes configuring backups of operating systems of their computers (physical and virtual) with Acronis Cyber Protect 15 (Console version: 15.0.4408, Server version: 15.0. 29486).
Initially, plans have been configured with the following characteristics:
- full backup
- Monthly
- Only backup of the operating system.
- All backups are kept stored.
The plans are executed correctly but I have noticed something:
- When the plan was first executed (the first month), everything worked well.
- When the plan was executed for the second time (the second month), the "Date modified" of the previous backup was automatically updated taking the value of the new execution date, the "Date created" was not modified.
- And so it happens with the following executions of the plan.
A restore test was recently performed using boot media (downloaded from https://download.acronis.com/AcronisCyberProtect15/Boot_media.iso) on a test server.
The test was successful only when all backups of the plan (in this case 3) were present. Although it could not be fully proven, but it seems reasonable, when only the first backup of the plan was present, the restoration process could also continue.
The test could not be completed when all the backups were not present, resulting in error messages that did not allow the process to continue.
I did not expect this behavior, since each backup is of the "full" type and I assume that they must be independent, that is, any of them should be able to be restored without having the others.
Please if someone can help me understand and resolve this. Maybe someone had this problem.
I wonder if what I mentioned at the beginning (updating "Date modified") is related to the second (all backups must be present during the restore)
Thanks for your help.
Hi Jose, thank you for you answer. I think I didn't give all the information
I copied the backups generated from a plan (all are of the "full backup" type) that I want to restore from the storage node of the Acronis administration server to an external disk, in a specific folder. The objective is to prove that it is possible to restore any backup using "boot media" and choose the backup from the external disk.I have 2 scenarios:
- When I have all the backups of my plan, from the first to the last, on the external disk (backupname.tibx, backupname-001.tibx and backupname-002.tibx), I am allowed to choose which of them to restore, I can complete the other configurations and the restore process is successful (even in this case, with hardware it is different)
- When I do not have all the backups on the external disk, for example if I only have the last two: backupname-001.tibx and backupname-002.tibx, I am not allowed to choose, appearing the error message with the title "The backup "is corrupted". And the restore process cannot continue.Please confirm if the test I want to do is possible. Or if there is something that needs to be done.
And also, I would like to know why with each backup generated from a plan ("full backup type"), the "Date modified" of the previously created backup is modified.
Thanks for your help.
Beste regards.

Hello Alex! Deleting the files manually isn't supported by our product. It's expected the files get corrupted and you see that error. You can just delete the files in the backup console and never outside there. If you follow this you won't have any issues with the recovery.
Best regards.
