1 Historically, dump was *always* used on unmounted filesystems. Tools like
2 AMANDA break that expectation. Backing up a live filesystem sometimes causes
3 problems for tools like dump, depending on what is changing while the backup
4 runs. If you see errors during a dump of a mounted filesystem, try again with
5 the filesystem unmounted, and see if that fixes the problem.
7 In theory, the page cache changes in the 2.4 Linux kernel can cause problems
8 to happen more frequently than in prior versions. Caveat emptor.
12 If you want to dump on remote tapes as a non-root user, you will need to make
13 the dump executable setuid root, so that it can allocate a priveledged port
14 for the outgoing network connection. This is not the default, since it is
15 not commonly needed, and setuid executables are targets for security attacks.
