Confusion about Restorepoints and Retention Policy

[SAPNWADM]

Hello,

i have a Backupjob with a retention policy of 40 Restore points to keep on disk. I trigger a Full Backup every Saturday via powershell script

Code: Select all

Add-PSSnapin VeeamPSSnapIn
Get-VBRJob -name "Cluster_ALL_10.10.10.120_D" | Start-VBRJob -FullBackup 

On every weekday i trigger 4 Incremental backups (08:00, 12:00, 16:00, 22:00) with the following poweshell script

Code: Select all

Add-PSSnapin VeeamPSSnapIn
Get-VBRJob -name "Cluster_ALL_10.10.10.120_D" | Start-VBRJob 

In the meantime i have 53 restore points for some VMs and Diskspace is running low.

I have 3 complete Backups and 50 incremental backup files.

Thank you

Are you using forward incremental backup method?

[SAPNWADM]

Incremental without "Create synthetic full backups periodically" and without "Active full backups periodically."

I had problems with the differnt time schedules therefore i had to trigger the backups jobs via the powershell scripts and taskscheduler.

This is due to how retention for forward incremental works. Provided I'm understanding your setup right, older restore points (oldest full + 20 corresponding increments) will be deleted once you reach 18 increments that depend on the most recent full (this will occur on Friday).
