Re: Backing up large Filesystems

Maybe because you are using dump instead of tar,
Amanda tries to dump the entire filesystem instead of content only?

Hello Amanda-Users,
maybe this is a very newby question, but i am running
amanda 2.4.4 to dump several filesystems to a DLT Tape. First backup went fine, but amanda seems to get trouble
with the large filesystems. One of them /var is about 70 Gig, but only 4% of it about 2.5 GB, are filled with
data. What ist amanda calculating to determine whether a backup fits on the
tape. Calculates it the overall size
of the Partition or the actual amount of data on that partition ?
I include an exerpt from the error mail
amanda sent me:
