You'd want to do more than one tar command of the form:
tar zcvf user1.tar.gz /home/user1/
tar zcvf user2.tar.gz /home/user2/
and so on. You'd have to specify the path of user1.tar.gz like where it
was going to go and the same for the other archive files too.
Home directories are on a seperate partition, what I want to back up is the
actual password/account list.
/etc/passwd seems to hold some of this, but it doesn't appear to show the
actual password hashes (unless cat is programmed to replace them all with a
'x').
The 'x' indicates that you have passwords shadowed (they are held in a
seperate file readable only by root).
You can either unshadow the passwords while you do the backup
(man pwconv) or just backup the shadow file along with everything
else, which is probably less trouble. You need to save these files:
/etc/passwd
/etc/group
/etc/shadow
/etc/gshadow
Since the shadow files are readable only by root, you'll obviously
have to be logged in as root to do the backup.
