Creating one full backup to rotated USB drives

Post by Brunok »

Hello,
we have configured rotated drive repositories (https://helpcenter.veeam.com/archive/ba ... igure.html) and created a backup job to this repository.

This is working, but often the old backups are not getting deleted correctly, so we tried to use the registry key for deleting the backups before the next run on the usb drive. (https://www.veeam.com/kb1154#:~:text=By ... b%20script)

We are not sure, how the best settings for the backup job should be. All what we need to have ONE FULLBACKUP (of different virtual servers) on one usb drive.

In the job settings we configured as follow:

Storage: (USB Repositroy) - Restore points to keep on disk: 1
Storage -> Advanced ->

Here is the question... do we need to create a reverse incremental / a incremental with synthetic full backups periodically OR a active full periodically ????

We only want to have ONE full backup each weekend on 2 different usb disks (changing the disks every friday).

i.e. Fullbackup_ALLVMSERVERS.vbk+.vbm / Disk 01 / Weekend 01
Fullbackup_ALLVMSERVERS.vbk+.vbm / Disk 02 / Weekend 02
Fullbackup_ALLVMSERVERS.vbk+.vbm / Disk 01 / Weekend 03
.....

At the end there should only be two files on each drive after the backup. A .vbk and .vbm

How to setup correctly ?

Thank you for your help

Hello,
just to be sure... you have the script that deletes old files?

Because the KB article states
regardless of rotated media setting, will maintain retention normally until the job detects that previously-available files are missing.
so if nothing is missing, then the backup job just works "as normal".

I understood that you want to delete all backup files on the rotated drive before next backup. Your script deletes everything as pre-script. That means, the backup mode does not really matter (because the first backup is always a full backup).

Best regards,
Hannes

Hi Hannes,
thanks.
No, we don't have a script. We just set the Reg-Keys as in the article:

Force Deletion of Files When Disks are Rotated
When this registry setting is enabled (set to 3 or 5), any repository, regardless of rotated media setting, will maintain retention normally until the job detects that previously-available files are missing.

Create this value on the Veeam Backup and Replication server:

Location: HKLM\SOFTWARE\Veeam\Veeam Backup and Replication\
Type: DWORD (32 bit)
Name: ForceDeleteBackupFiles
Value: (seee below)

so, if the disk (directory) is empty each time, the settings on the job for "reverse incremental OR a incremental with synthetic full backups periodically OR a active full periodically" are obsolete, as it always start with a full backup ?

We had problems when not deleting the files, sometimes the retention policy did not work, the old backups were not deleted and filled up the diskspace.

Regards
Bruno

Right, in a rotated droves scenario, with every backup method Veeam B&R will create the new full in case it is not able to locate the previous chain.
