I would install xfsdump/xfsrestore and "rpm -e dump" and then run ./configure script, then it should find xfsdump and choose that as the OS dump program. Then you would assign a non-GNUTAR dumptype to the disk(s) and it should run xfsdump for the backups. Hopefully, the configure script does not check to see if the OS is IRIX or not Linux and decide that xfsdump can't be installed on the system--Then you would have to hack the configure script a little bit to get it to work properly. -- "Jonathan F.

Amanda should auto-detect the file system type and run the correct dump program (assuming it found it when you ran ./configure). For instance, it flips back and forth between ufsdump and vxdump on my Solaris systems. If it doesn't do that for you, we need to work on that. >C. Chan John R.

I've been using GNU tar under Linux since I've trusted dump for ext2. Now ReiserFS does not have a dump util as far as I know. XFS does have xfsdump which has behavior in between tar and dump (does filesystem access rather than raw device but does not touch atime) so you may try converting to XFS. IBM JFS under AIX's backup util has filesystem and inode backup modes but I don't think their dump for JFS is ready yet. I don't know if anyone had tried BRU with Amanda but it has tar-like syntax and may work without much difficulty. I'm experimenting with XFS now and if I run into any glitches I'll let the Amanda list know. I'd like know how to tell Amanda to use xfsdump rather than GNU tar on XFS partitions. -- C.

Dumping live filesystems on Linux 2.4 -> Corruption
I am sure everybody has seen this: http://www.lwn.net/2001/0503/kernel.php3 It would seem that one can no longer use dump (assuming one is using Linux 2.4) to backup live filesystems. So is everybody here now using gnutar to backup filesystems on Linux 2.4? Is there any loss of functionality to using gnutar? b. -- Brian J. Murrell
