Full backup every X don't work

[vdeville]

Hello Thanks for your tool, i install on proxmox 6.1.8, no problem to patch. The first backup is process as full, this is fine. But the parameter --fullbackup is not applied.

My command : vzdump 103 --mode snapshot --compress lzo --storage local --fullbackup 4

After multiple exec of the command, only the first full backup is present all others is diff.

Do you have an idea of what is wrong ?

Thanks

This works fine. The fullbackup indicates how many full backups can be persisted. The differentials are controlled by amount of days of keeping them before a new full backup is created.

Hello I will retry in the next days, in the past this comportement doesn't work. Thanks

Hello @ayufan Just tested today with theses settings and create more than the max backup set, and always make differential.

Thanks

Because it count not backup-instances but days
