We currently use dump as a backup utility due to limited budget. However, dump has been giving us fits due to lseek errors. Someone suggested looking into LVM, so here I am. I looked a the website and did a little digging, but I was unable to find out if LVM will serve my purposes. If anyone can lend a hand and provide feedback that can tell me if LVM is worth my effort to solve this problem, or where I can find this sort of information, I'd be vert greatful.

Dumping dump might be the first thing that would help. It's old and tired and deserves a rest... For free utilities you can get better speed and filtering with cpio, which backs up from the file system rather than inodes. At that point LVM is a nice solution for managing anything large enough to be backed up. -- Steven Lembark 2930 W.

Have you considered using cp -aux? It should restore hardlinks. -- Lewis Bergman Texas Communications 4309 Maple St. Abilene, TX 79602-8044 915-695-6962 ext 115 ^ permalink raw reply [flat|nested] 6+ messages in thread

Have you looked at afio (and it's -4 option for dealing with more than 64k hardlinks)? Be sure to read the 'BUGS' section as well. Oh, and afio can compress the backup -- by compressing 'per file', thus corruption only kills the affected files. -Wolfgang ^ permalink raw reply [flat|nested] 6+ messages in thread

To copy data from one filesystem another, preserving hard links, I use: rsync -avxSHW /source-dir/ /target-dir -a same meaning as for "cp" i.e. recurse and copy metadata -v be verbose -x do not cross filesystem boundaries -S handle sparse files -H handle hard links -W only copy whole files Trailing slash on source-dir makes it copy *contents* of directory rather than directory itself. It only copies changed changed files. Be sure to use version 2.5.2 or higher of rsync. Bill -- William H.
