Backup before upgrade/reinstallation

Administrators

We’ve migrated our indico server from CentOS7 to Ubuntu 24.04 last year, and it is time (summer activities) to adjust the server/system.

My understanding is that it is prerequisite to backup the indico system manually before any upgrade or reinstallation. What happens when someone forgets about backing up? Does it wipe out the DB which stores past workshop and conference information?

Thanks in advance,
Doris

Typically updates do not result in any data loss. But backing up data is generally a good idea just in case. Better safe than sorry. :slight_smile:

The only case where you are absolutely required to create a backup of both the database and uploaded files is of course when you reinstall the machine itself.
