Fine. No problem. I do that once a week, but use tapes (220 Gbyte).
The tapes are stored offsite.
intermediate tapes but would like to take a monthly snapshot of the
archive. It will fit on a DVD so we're not talking enormous backups
here. What configuration does Amanda need to extract a compress full
monthly dump?
I don't understand this question, I believe.
What is a "compress full monthly dump"? If you mean a gzip-compressed
tar (or dump) archive, then you only need gunzip and tar (or restore)
to extract the data.
Having amanda utilities available, like "amrestore", helps, but it
not a requirement (use "dd bs=32k skip=1" to jump over the amanda
header to the "compress full monthtly dump", as explained in docs/RESTORE).
Can this be done through amrestore? Is there any way to dump a
compressed amanda archive to a file?
??? It is a file already? Or do you mean the "compressed tar/dump"
image just after the 32k byte header amanda adds? (That header
even contains the commands you need to extract the backups!)
> And doesn't amanda spread full
dumps througout the dump cycle anyway, making it hard to get a complete
dump of lots of entries in disklist at the same time?
Spreading over a dumpcycle of "0" days is what you want.
Make a separate config named e.g. "Archive" and set "dumpcycle 0".
Run that config on the needed day instead of the daily.
