ArcServe and Netware are probably the only two pieces of software I
can
easily justify purchasing.
So. . . If you want tape backups, buy ArcServer and Netware because it
doesn't work on Linux?
Forgive me if I disagree.
Whilst the whole rsync or other on-line solution is fine for those who
want that, my solution was a little more direct: use dump (ufsdump on
Solaris). Don't use dump on Linux, it won't work (so says Linus: http://dump.sourceforge.net/isdumpdeprecated.html
, except the links don't work. Sigh. I can't find the direct
link.). At least not on live filesystems.
However, if you OS supports it, using snapshots will work, and get you
what you want. Even if you dump to a file instead of tape, it works
quite well. And you can have nice rotations and everything. I use an
SSH key to run a dump command on my selected filesystem (using
snapshots is trivial in Solaris now, on UFS filesystems).
Of course, you have to think about your backups. But I think it's a
worthwhile investment to actually think about your backups, your
rotation and retention schedule, and not just trust the vendor.
