Home Assistant backup retention

[micky-bamboleo (Micky)]

Hey there,

I again ran into a full backup storage and as my „backup backup solution“ (backup HA vm in proxmox) also failed unrecognized for quite a while and I recently destroyed my instance I just lost data and configurations of multiple weeks

Is there any known possibility or workaround for creating a backup retention policy in Home Assistant for example via an automation?
I imagine something like keeping the last two weeks of backups + 1 of each month for the last 12 months.

I only found this feature request from 2022 which doesn‘t seem to be very popular though:

Retention policy for backup integration

It would be nice if the backup integration would get some kind of retention policy, for example “delete backups older then X days” similar to the recorder. I currentely solve this through executing shell script that delete the backups in the file system. While this is working it’s not really convenient.

How do you guys solve this?

Thank you and best regards
Micky

The samba backup add-on backs up to another device, retaining the last x backups on HA. I backup to my NAS and keep them all, with only the last 10 on HA itself.

The samba backup add-on backs up to another device

Yes, this would be my solution too. I do the same, I keep 1 original and 10 days of backups. But the deleting the backups are manual. I’m sure I can write a script for my NAS to delete older backups.

I use the same addon and it automatically deletes old backups on the remote share. Are you sure you have configured it correctly?

Thanks guys for the replies, indeed I already used to use this addon too but seem to have missed the retention functionality. I will have a try and report again!

Now that we have the option to save HA backups to an SMB share, the only feature missing from HA is the backup retention, compared to Samba Backup. Anybody got solutions for that?
