There have been *many* threads on this in the past, so check the archives. Hopefully this won't flame up again. In short, use what works for you. Dump has advantages in certain circumstances. For example, xfsdump (for XFS filesystems on Irix or Linux) saves ACLs, whereas tar does not. > 2)I'm using amanda with "dump" for 8 months and now every run we are > almost fulling a tape. > -I change the disklist by replacing the nocomp-user with user-tar > -I thought that in this way the transition will be smooth. > > obsul35 /export/diskA1 lev 1 FAILED [dumps way too big, must skip incremental >dumps] *snip* > > So I'm strongly suspecting that amanda is not stocking the information > of: > -what was done before > -and what it has to do. Well, dump uses /etc/dumpdates to store its history. amanda creates /etc/amandates to store tar's history. So, in switching to tar, amanda no longer knows when the last level 0 of any filesystem was (since /etc/amandates is presumably empty). However, I would strongly advise against simply putting the dates from dumpdates into amandates. You're using a new backup program now. I would try to get a tar level 0 of every filesystem ASAP. Amanda should do this on its own. -- Joshua Baker-LePain Department of Biomedical Engineering Duke University
