Is it possible to add an environment variable to control how many full backups to keep?

[Jack187]

Hello,

thx for the great tool. I started using it today, but I'm missing the option to only save 2 (or n) full backups.

I'm currently using the following environment variables:
-e "VOLUMERIZE_JOBBER_TIME=0 */5 * * * *" \ (for testing purposes all 5 mins a inc backup)
-e "VOLUMERIZE_FULL_IF_OLDER_THAN=1h" (for testing purposes after 1h a fresh full backup)

here is what I found in the duplicity man page:
remove-all-inc-of-but-n-full [--force]
Delete incremental sets of all backups sets that are older than the count:th last full backup (in other words, keep only old full backups and not their increments). count must be larger than zero. A value of 1 means that only the single most recent backup chain will be kept intact. Note that --force will be needed to delete the files instead of just listing them.

As I'm new to docker, Is there a way to achieve this with the current version of volumerize or is it something that needs to be added?

Thx for your work!

Bye,
Jack

Do we still need something in this ticket?

@Jack187 I think this is solved by #7

What do you think?

[blacklabelops]

In this form I think it is solved by #7.

Later on we can think about a Maintenance Mode where you can define several parameters for maintaining long time backup archives.

Yes, it's solved!

I tested it with following configuration:

-e "JOB_NAME2=RemoveAllButNFull"
-e "JOB_COMMAND2=/etc/volumerize/remove-all-but-n-full 2 --force" \

Thanks for adding! I really appreciate it.

Cheers
Jack
