Hello,
while preparation our upcoming Lemmy update we’re also be updating to a newer database version, which will provide additional performance benefits and functionality.
We are planning for around 10 minutes of downtime for the database update between 19:00-19:30 UTC on 22nd of February. This is not yet the planned Lemmy update, we will be announcing that separately when we are ready.

incremental backups might also be something worth looking into
