Well, /bin/sh and 'man sh' spring to mind. :-) Or use another scripting language if you are more familiar with that, e.g. perl or python. But since you are mainly invoking programs, a plain shell-script would be my first ch= oice. > From what you are describing a tool that would automate the dump process = and > take care of snapshots versions would be a must=E2=80=A6 ?? See e.g. the dodumps script on my scripts page; http://www.xs4all.nl/~rsmit= h/software/scripts.html It just names the dumps 'filesystem-dumplevel-date.dump', e.g. root-0-20091217.dump. You could extend this script to transfer the dum= ps via ftp, and remove old dumps from the FTP site. After testing, you could e= ven run it from cron. Start off with a level 0 dump, and then perform higher level dumps as often= as you need. Google for 'dump levels', and you'll find lots of different schem= es, e.g. http://docs.sun.com/app/docs/doc/817-5093/bkupconcepts-21?a=3Dview I would urge you to keep things simple. The more complicated the your solution, the easier things can go wrong. One caveat about dump though. If one of your filesystems contains just one = big database in a huge file, dump will copy the whole file even if just one byte has changed. In such a case you should see if the database has tools to just copy the records changed since the last backup and use that instead.
