Full backup - new long-retention options
-
@Bastien-Nollet here is the config of the BACKUP job :
to the remote DC1-REMOTE01
you would expect 10 points after 1month+ of forver incremental backups ?
7 daily, 2 weekly, and 1 monthlybut I only get 7 points in this remote (the last 7 days)
I have a mirror copy job, 14 points retention, no LTR, to a remote called DC2-REMOTE01-COPYDC1, i get my exact 14 points.
so i guess, i do not profit from LTR ?
is that because i didnt put something in DAYS ? or because my retention is >1 ?
backups are executed daily by SEQUENCE. -
@Bastien-Nollet said in Full backup - new long-retention options:
@Forza As your backup tasks executes only once a week, the schedule retention is redundant with using "Number of weekly backups kept" of LTR.
If keeping the last 52 weekly backups of this job is what you want, I recommend you to set the schedule retention to 1, and the number of weekly backups kept to 52. This way, if you happen to execute this backup job manually (in addition to its schedule), it will not delete the oldest backups.
Thanks for the feedback. I included that difference (52 in the schedule and 12 in the LTR) on purpose in the screenshot because I wanted to know what takes presendece here, the 12 weeks, or 52 weeks.
I have not yet enabled LTR, but am considering it for this backup job so that I can keep 52 weeks, 24 months and 5 yearly.
Now I wonder if each dailym weekly, monthly and yearly option are sequential to the previous, or if all counts from 0?
Will it mean that I have:
- year 1: 52 weekly
- year 2: 12 monthly
- year 3: 12 monthly
- year 4: 1 yearly
- year 5: 1 yearly
- year 6: 1 yearly
- year 7: 1 yearly
- year 8: 1 yearly
Or will I get:
- year 1: 52 weekly + 12 monthly + 1 yearly (at the end of year 1)
- year 2: 12 monthly + 1 yearly
- year 3: 1 yearly
- year 4: 1 yearly
- year 5: 1 yearly

Hi @Pilow,
You're indeed supposed to have more backups kept. (probably 9, as the backup of the current week is already kept by the schedule's retention).
We'll try to reproduce the problem on our side to see what's going on and fix it, but it will be a bit long as testing it requires a lot of waiting.
Thanks for the feedback, it will help us improve the feature.

Hi @Forza,
The first list is the correct one.
For instance, a single backup can satisfy both the monthly and yearly criteria. -
@Bastien-Nollet by default what day of day/week/month/year is selected for the LTR point ?
You said we cannot choose for now, but you could give us the actual recipe ?
-
This is supposed to be the first day of the year, of the month, etc... But we just noticed a bug that makes LTR keep backups from the end of month, end of week, etc.
A fix is on the way.
-
@Bastien-Nollet Some countries use different days for first of the week, This should perhaps be configurable for such users? I prefer Monday as first of the week
-
We plan to make it configurable during the upcoming months.
-
A fix has been merged on master, now the LTR should properly pick the first backup of each day, week, month and year instead of the last one: https://github.com/vatesfr/xen-orchestra/pull/9180

@Bastien-Nollet
I have tested it since the 05c6f release and it seems to work fine
