Odd backup files

I got a warning today about low space so went googling…

From poking about the OS I could see my backup folder was way too big.
Went to Settings > System > Backups and found a bunch of old stuff I cleaned up but could still see some big old files.

I use the Google drive backup addon and that reports 2 local copies which matches Settings > System > Backups and 5 on google.

➜  /backup ls -l -t

The top two are the most recent backups of 255mb odd but what are the rest and can I safely delete them?

Hello…

With every update of an integration, addon or such it asks you if you want to perform an update upfront…a flag easily overlooked.
And so u might end up with some big full backups and some small ines due to the amount of updates that r coming out…
Normally u can delete all backups as long you dont plan to recover anything from them…
I have the samba backup addon running full backups every sunday and store tham on my nas…rest gets purged

Cleaned them all up apart from the most recent 2, massive space saving on the disk…
