I just stumbled over an email from Linus stating the following: << snip snip >> "Note that dump simply won't work reliably at all even in 2.4.x: the buffer cache and the page cache (where all the actual data is) are not coherent. This is only going to get even worse in 2.5.x, when the directories are moved into the page cache as well.
So anybody who depends on "dump" getting backups right is already playing russian rulette with their backups. It's not at all guaranteed to get the right results - you may end up having stale data in the buffer cache that ends up being "backed up". Dump was a stupid program in the first place. Leave it behind." << end snip >> Read whole thing here: http://www.cs.helsinki.fi/linux/linux-kernel/2001-16/1175.html Anyhoo, I find myself currently using the Reiser filesystem, and I am now considering backing up critical config files and directories on my servers with tar and rebuilding them from scratch using XFS since that filesystem has a working version of dump ('xfsdump'). Any comments, advice? (Does Amanda even work with xfsdump/xfsrestore? Thanks, Scott Phelps
