[Koha] Daily outage during backups

[Tomas Cohen Arazi]

You should check CPU and I/O. It is taking too long and I guess resources
are not enough to run all the things.

If you manually run:

$ koha-dump <instance>

What takes most of the time? DB? Files?

Do you have a huge /var/lib/koha/<instance> dir? Are you running your
backups with --exclude-indexes?

Those are the questions I would start with.
