Following up the MAAS backup procedure documented in https://maas.io/docs/deb/3.0/cli/backup
I ended up having really big tarballs:
14.11 GB tgz for one server and 3.58 GB tgz for another.
These servers were in use for some years so I guess it accumulated some data.
The biggest file is always the database dump, uncompressed:
-rw-r–r-- root/root 7158718116 2021-09-23 14:39 tmp/tmp.mVB74Yv84C/dump.sql ~ 6 GB
-rw-r–r-- root/root 27185012810 2021-09-26 11:08 tmp/tmp.somE6SEH8U/dump.sql ~ 25 GB
any idea if one could cleanup the DB to not drag this huge size over time?
