Thanks. I've read the documentation and didn't see any hints that such thing would be possible.
Request: Optional monthly backups
- Thread starter Ivan Gonzalez
- Start date
Jep, atleast the documentation doesn't mention that dates will work: https://pve.proxmox.com/pve-docs/pve-admin-guide.html#chapter_calendar_events
I found that indeed, however i must apologies and still do not get how to do this 1 time per month.
One per week isn't a problem, only once per month. If you want a weekly backup at 00:00 just type in "0:00". You are not limited to the predefined values.
That will work now too with pve-manager version 7.1-9 (and dependencies), currently on the pvetest repository.
As there we switched over from the old Perl implementation, which was initially added for Proxmox VE 5.0's new storage replication in 2017, to the rust based from PBS. The original calendar event implementation application (storage replication) just did not need such intervals like monthly, so it wasn't added there initially.
So with 7.1-9 or later a schedule like
sat *-1..7 15:00 (first Saturday in month @ 15:00) or just monthly (first day of month 00:00) will work.

There's an example for that in the editable selector,
sun 01:00 schedules it every Sunday at 01:00 in the morning, if you want another day or time just replace the respective part.

Hi, If I want to schedule for Monday and Wednesday, what should I put? "mon,wed 02:30" is this right? It has let me do the task but I don't know if it is correct (other possibilities I have checked told me that the syntax was incorrect and would not let me create the task).

Yes, 02:30 o'clock on monday and wednsday would be described by the
mon,wed 02:30 calendar event you used.FYI, there's a schedule simulator available to help with ensuring one got the correct spec:
Hi, is there a way to schedule a backup for just every 2nd Monday of a month?
Till now I couldn't find out how to make it work.
Thanks.
Hi,
). There also is a schedule simulator in the upper right corner of the
yes, you can use
mon *-8..14 15:00 (only the second Monday will match a day between the 8th and 14th inclusive ). There also is a schedule simulator in the upper right corner of the Datacenter > Backup where you can play around with or verify schedules.
Well yesn't, it really depens on how strict you require that to be, as currently systemd calendar events, which we base on here as common standard for flexible time schedules, lacks support for a biweekly (or any fixed day repetition not equal to exactly having a period of a week, month or year) cannot be expressed, there's an issue open for that on upstream systemd, and some activity plus a draft pull request got submitted in the recent months, once this is actually included and so the format and details are fixed we can add this to our scheduler too.
Until then, the closes you'd get is to adapt the example for first Saturday by changing
sat to mon and add a second day range with comma separate to extend the first one, the end result is then: mon *-1..7,15..21 15:00 - should be pretty close, but I think there are some edge cases where the period isn't exactly two weeks, but you're guaranteed to make a backup on the first and third monday, every month, if that's enough.Hi,
many thanks for your both replies @fiona & @t.lamprecht
this is what I was looking for, for the time being.

How can I achieve to run backups to an "odd" storage on a odd week and to an "even" storage" on an even week?
I have tried with the simulator but it was unsuccessful

Hi,
AFAIK, that's currently not implemented and since we base the schedule format off systemd, we'd probably wait until it's implemented there too and then match their syntax: https://github.com/systemd/systemd/issues/6024
This example "mon *-1..7,15..21 15:00" does not work for me, I get an error message,
