I did grep on amstatus output, see below

[amanda@backup ~]$ amstatus Full1 | grep dumping

I have enough space om holding disk, it's about 100Gb

Actually I want dump to backup different computers at once and then I'll
enable spindle feature. I'm running amanda-2.4.4p2-3 (FC2) on server and
amanda-2.4.[2-4] on clients. Should I upgrade to 2.4.5?
