I have a couple C5 systems I want to back up. My plan is to, one way
or another, back them up to a C5 machine in my office. I have samba
installed on the systems to back up, the machines are mounted on the
system in my office, and a tape library hanging of the system in my
office.
I was hoping to perform a simple /sbin/dump of the remote systems. I
put together a script for another successful backup I have going on a
system with local filesystems. But for remote filesystems, I get
errors of File Cannot Be Accessed (//remote_system/subdir) which does
exist as an smb mounted filesystem.
I'd use NFS, but I would like a bit more control and some level of
encryption for the user authentication and data being transferred.
If a direct dump of remote smb filesystems isn't possible, I may opt
to have each system perform their own local dumps, then run a script
locally on the tape-connected machine to dump those local dumps, or
copy the dumps locally then dump them to tape.
If nothing else works, I can always install Windows XP and use
Windows backup program, but I'd really like to try and get this going
under Linux before going that route.
use amanda, www.amanda.org
it rocks
My fundamental question is why dump claims it cannot access what I want
it to back up. What's to say other solutions - Amanda, etc, will work
any better? I want to know how to resolve the source problem before
looking into other products. How will BackupPC or Amanda do any better?
Dump is file-system oriented and won't handle remote-mounted
directories. You can use file-oriented tar on remote mounts - or smbtar
on remote samba/windows shares without mounting them, or use ssh to run
some command like tar or dump remotely and return the output.
Amanda works by having a remote client do the work and return the backup
data and can use tar or dump. Backuppc uses ssh with tar or rsync, or
smbtar or rsync against a remote copy in daemon mode, thus not needing a
dedicated remote agent.
Amanda is more tape-oriented, but can also archive to disk. Backuppc is
best at archiving to disk (with some clever tricks to reduce the space
needed) but can also write to tape.
