Per-Machine Chain and Backup Copy to rotated drives

Post by melexis »

Hi,

since Veeam B&R 12 I can enable per-machine backup also for my rotated drive repository, means both checkboxes are enabled:
"This backup is backed by rotated drives"
"Use per-machine backup files"

It works so far, on our rotated drive I get separate vbk/vib/vbm for each VM.
But there's somthing written in the User Guide that worries me:

https://helpcenter.veeam.com/docs/backu ... ml?ver=120
"Limitations for Backup Repositories with Rotated Drives
Backup repositories with rotated drives have the following limitations:
You cannot store per-machine backup files in backup repositories with rotated drives."

https://helpcenter.veeam.com/docs/backu ... ml?ver=120
"Limitations and Considerations for Per-Machine Backup Files
When planning to use per-machine backup files, consider the following limitations:
The Use per-machine backup files option cannot be enabled for backup repositories with rotated drives."

So why can I enable both checkboxes? Why is it working so far?
What really happens or will go wrong when I use per-machine backups with rotated drive repository?

Hello Melexis

It may be a documentation issue.
Let me check with QA and Tech Writers.

I forgot to mention I currently use the rotated drive repository for Backup Copy Jobs, just in case this is somehow relevant.

Hi Melexis

For new Backup Copy Jobs in V12, per-machine backup files is mandatory.

Hello Melexis

Per-Machine backup files on Backup Repositories with Rotated Drives are now fully supported in V12.
We removed the limitation from the user guide.

Thank you,

Hi,
I have been using rotated drives for a number of years. One disk for each Monday to Thursday, with the disk swapped on the respective the day the following week. And another 4 disks representing the Friday relative the week of the month. Backing up 15 VMs, I have split them up into 4 different backup jobs (relative to their importance and schedule) backing up to a folder on the disk relative to that backup, In the Properties of the Repository, I have last 2 options checked.

When the daily disk from the following week is loaded, sometimes Veeam will do an Incremental and continue the chain. Other times it will ignore the chain and create a new VBK file. I cannot find any pattern, that is, it might create one vib or 10 vib files before it creates a new vbk.

Ironically, I found it more reliable in earlier versions when per machine backup was not an option.

Any ideas
Thanks, Greg
