Hi. There are a couple of parameters on amanda.conf that I can't
figure out exactly their meaning, even after reading the man pages a
thousand times:

- dumpcycle, in days
- runspercycle, in number of amdumps
- tapecycle, in number of tapes

tapecycle is the total number of tapes; only these tapes are rotated,
right?

runspercycle is in how many dumps the whole backup is spread? a
runspercycle of 4 means that the last 4 tapes contain everything to
recover the whole system? not sure about this...

what is dumpcycle? is this how many days can pass after which a backup
must exist?

and a problem I have is understanding what happens whenever I skip
amdump for a couple of days. Because of the dumpcycle, it means that
next amdump will dump a lot more than usual?

and let say I just require a weekly backup; if I set dumpcycle to 7
days and runspercycle of 4, it means that it only takes 4 tapes to
have a full backup? But I can lag until 7 days.

Thank you,

Rodrigo
