You could run two dumps in parallel, one with tapecycle of 7 onj your local

Hi,
I noticed that the command

ends with giving the size of the data transfered, but the message is
slightly different and Amanda cannot parse the size

- do you have enough space on your disk for Amanda to copy the files
from holding to tape: it is not just moving files around, but it is a

is good that usually you can do the test

Then you install with root account: you need root proviledges to install
because you need to create directories where other users can't, you may
need to create new users too (like user amanda).

ow to implement the
backup? If two DLE contains the same file, that file should exist in a
single location on the physical hard disk. But a backup of each DLE will
have a copy of that file, so the size of the backup will be biger than
the orginal disk. Am I right?

Problem is not the time, but more of strategy:
It seems that there is an estimate full run every day, even if the
dump ends up being incremental.
If I do my full copy just before the full estimate, I will end up
doing a full copy every day, that defeates the purpose of having
incremental copy.
