Incremental backup software for a mixed environment
I'm setting up a home server with Ubuntu 8.10 and I want backup software that does nightly backups of files located on shared folders. Some folders will be from Linux boxes, some will be Windows shares.
If the folders are mounted on the machine that will hold the backups, you can simply use rsync & run it on a cron job.
then, to run it nightly, simply run "crontab -e" and add the rsync like so:
0 - the 0'th minute of the hour (i.e. 1:00 or 12:00 or 5:00)
0 - the 0'th hour of the day (i.e. midnight)
* - every day of the month
* - every month of the year
* - every day of the week
... so it will run at midnight, every day.
you can have several lines in one cron to do all backups like so:
which would copy the directory /mnt/windows/my_mp3s and its contents into /home/EarthAndAllStars/backups/windows/, copying only changed data, deleting files in the backup location that have been deleted on the share, and maintaining all file information like timestamps and such.
This is all a "pull" from the backup machine. If you're looking for a push from the windows machine.. well.. maybe that's a question for WindowsQuestions.org. ;) (which is to say, I don't have a good answer that doesn't involve installing MS's UNIX Tools so that you get rsync & cron jobs).
