Amanda, by design, does not do a full level 0 backup of all disklist entries at the same time, instead, it tries to scatter them out among the backup runs during the dumpcycle so that it uses about the same amount of tape per run, but a dumpcycle can actually contain 5 to 7 tapes (the way most do it) with each tape filled to 95% or more of its capacity.
That said, there is a patch for amanda that will allow it to span one individual backup over more than 1 tape. I'm about to apply it here, and play with it over the next weeks to see if I can break it. It lives here: <http://www.cs.umd.edu/~building/span_split_V7.0-2.4.5b1-20050214.patch.gz> and is against the last 2.4.5b1-20050214.tar.gz version of amanda, available from a link near the bottom of the amanda.org web page. >-----Original Message----- >From: [EMAIL PROTECTED] >[mailto:[EMAIL PROTECTED] On Behalf Of Jon LaBadie >Sent: Monday, February 28, 2005 11:58 AM >To: amanda-users@amanda.org >Subject: Re: Dump larger than tape error > >On Mon, Feb 28, 2005 at 01:35:15PM -0500, Byarlay, Wayne A. wrote: >> Hi, all! >> >> /usr/local/var/amanda/gnutar-lists/luke.lib.purdue.edu_var_0.new: > >Cannot > >> write: No space left on device >> >> | Total bytes written: 3040256000 (2.8GB, 8.9MB/s) >> >> ? gtar: Error exit delayed from previous errors >> sendbackup: error [/usr/local/bin/tar returned 2] >> \-------- > >_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+ >_+_+ > >> _+_+_+_+_+_+ >> >> Now, the disks I'm using to do my backups is not full.
