Re: [Duplicity-talk] Remove old incremental backups

[Сергей Цаболов]

Hi,

Thank you for answer and help.

I try to remove all in incremental backup on one of VM and all incremental backups are deleted (to save the storage space) and let only the full backup for 16.10.22

root@vm1:~# duplicity remove-all-inc-of-but-n-full 1 --no-encryption --force file:///srv/duplicity/ --log-file /srv/remove.log 2>&1 | mail -s "Duplicity remove-all-inc-but-n-full 1 Complete" tsabolov@t8.ru
root@vm1:~# duplicity collection-status file:///srv/duplicity/
Last full backup date: Sun Oct 23 03:10:01 2022
Collection Status
-----------------
Connecting with backend: BackendWrapper
Archive dir: /root/.cache/duplicity/afe4481beef92be2af167e0e61a6488d

Found 1 secondary backup chain.
Secondary chain 1 of 1:
-------------------------
Chain start time: Sun Oct 16 03:10:01 2022
Chain end time: Sun Oct 16 03:10:01 2022
Number of contained backup sets: 1
Total number of contained volumes: 16
 Type of backup set:                            Time:      Num volumes:
                Full         Sun Oct 16 03:10:01 2022                16
-------------------------


Found primary backup chain with matching signature chain:
-------------------------
Chain start time: Sun Oct 23 03:10:01 2022
Chain end time: Mon Oct 24 06:30:01 2022
Number of contained backup sets: 3
Total number of contained volumes: 18
 Type of backup set:                            Time:      Num volumes:
                Full         Sun Oct 23 03:10:01 2022                16
         Incremental         Sun Oct 23 06:30:02 2022                 1
         Incremental         Mon Oct 24 06:30:01 2022                 1
-------------------------
No orphaned or incomplete backup sets found.

Thank you, now I think on some VM automated remove some   incremental backups once of 3 weeks, I think can add it to crontab to remove.
