OK Thanks.
BTW, found a note in the Amanda mailing list (where this is a recurring
flame fest) referring to a note on one of the kernel mailing lists that
the cache-coherence problem with dump was resolved as of Linus's 2.4.11.
I don't know if that fix is universal (or at least in Red Hat's kernels)
now with 2.4.18, but if so, it reduces the problem somewhat. Now, as I
understand it, at least dump will make correct backups of unmounted file
systems or in single user mode. "Quiescent" mounted file systems should
also be OK. Not sure yet of the impact on ext3 file systems, though, but
it seems like it ought to be the same.
I'll probably stick with tar, though I understand it's slower. Is
Gordon's comment about extended FS attributes a reference to non-ext2
FS's? Are there other disadvantages to using tar with Amanda?
Thanks.
