Dear friends,
What are some popular tools for backing up the file system? Is dump
still popular? What are alternatives?
Before you pick a tool, decide if you want a backup which is best for
restoring the whole system after a major failure, or just something to
keep old files in case you need them.
Tools like rsync are good for a mirroring, but in general they are lousy
backup, if you delete a file, or mess it up, unless you catch it quickly
you now have two copies of the problem.
Tools like tar/dump/star/cpio make a backup and can easily make
incrementals as well. You can keep those as long as you feel the need,
and decide if each incremental is the data since the last full or last
incremental backup, choosing speed of restore or of backup, fast restore
of all files, or fast access to just one.
This is one of those cases where it's easier to solve the problem if you
define it first, there's no perfect solution I've found.
