On my file server I have 2 drives.
I also have two drives on each of my machines. One for backup. I also keep several days worth of backups in case I corrupt a file. Overall I think I have the data part of the backup covered properly, although I plan to backup some directories every few hours instead of daily.
- Unison : 2-way synchronization using rsync/ssh, multi platform
I use unison to backup data from a remote machine to my local machine,
- rsync : typical rsync that will mirror the source to the destination
Why use both unison and rsync? Unison can do the same as rsync.
I made two mistakes in my description.
- rsync-backup : it's based on rsync but you get the advantage of
incremental backups so you can restore from a specific date. You can
also purge the backup by removing old stuff.
Will look it up.
First the tool is call rdiff-backup (and not rsync-backup which also exists) : http://rdiff-backup.stanford.edu/index.html
Secondly, for the OS, I also use rdiff-backup and not rsync so I have a fast, space efficient, incremental backup of the OS too !
PS: On the same web page you will also find a link to another tool call duplicity (http://rdiff-backup.stanford.edu/duplicity.html). You can do remote backup but in that case the image can be stored on a remote FTP server and encrypted with GPG... sweet if you're planning to use the disk space of your ISP for backups!
A couple of cron jobs take care of the different backups at night.
Same thing here, except that I plan to do some dierctories more often (ie emails).
I don't know if that answers to your question but I thought that could
give you some ideas.
Didn't really answer what I asked, but all suggestions/feedback/comments
on how other people are doing things are always welcome. It helps to see
other possible solutions to what one is doing. I am a firm believer in
learning from the experience of others if they are willing to dedicate the
time to share their experience with me. :-)
