[SOLVED] Backup retention rules

[bly]

Hello,
I'd like have last 4 daily, plus last 2 weekly, last 6 monthly, and 1 yearly backup, and I had set the retention accordly as in figure:



After a week of running daily backups, I see in content only the last 4 daily backups, but not the first backup I did a week ago:



How I correcly have to setup retention (or backup job) in order to have the intended behaviour?

Hi,

The prune settings in Proxmox Backup Server define how many backups to keep for a given period. Did you see https://pbs.proxmox.com/docs/prune-simulator/index.html ?

AFAIK the cycle reckoning for weekly retention, uses Sunday (last day). Your retention includes a backup for the 14th of April. So you have a weekly-retained backup.
Give it another few days - and you should have 5 backups - including that of the 14th (Sunday).

Thanks for pointing me up that Weekly retention uses Sundays.
From the simulator I see Monthly uses the last day of the month.
I expect the yearly using the last day of the year?

I will check the incoming Monday to see the weekly backup but I guess it will be ok

I wonder... if I don't do any backup on Sundays, I'll never have any weekly backup retained?
I mean, if I backup only on the end of working days because I don't need backup of the days no one uses servers, is weekly retention failing?
Maybe which day of the week to use for retention use is set up somewhere I can change?

You may wonder - but I'm pretty sure it will keep the most recent backup for that week ending on Sunday; irrespective on what day of that week the backup was made.

Edit: Just tried it in the simulator - and is as expected.

Nice to know!

It will keep the last backup done that month, no matter what day of the week it got taken.
