    Thank you everyone for their help.

    Yes. FAT32 has all kinds of restrictions, caters for limited filesize, and doesn't work well with rsync (which Backintime uses). EXT3 is best, but if you need to access it directly from a Windows machine you can get away with NTFS I believe.

    Rather than focusing on the details like CLI or app, think about your backup strategy in general and what sequence events would follow if you had a failure. That will determine your strategy.

    As an example here's what I do:

    I don't backup the OS, I am prepared to reinstall from DVD if I lose the OS, since it doesn't take long. Getting all updated might take a while, but it shouldn't take me long to have something usable.

    I do backup key files in /etc and other places that carry configuration information though to DVD-RW about once a quarter. Maybe I should do that more often.

    I backup my home directory to an external disk once at midweek and to DVD-RW at weekend. The latter is automated from cron. My personal files, email, etc. still fit on a DVD.

    Media and other stuff I archive to DVD-R while leaving them on disk (but not included in the regular backups).

    One area in which I'm not well protected is offsite backups. I recently gave a friend an encrypted DVD of my personal files. Perhaps I should send out DVDs more often.

    =====

    External disks are good in that you can recover stuff quickly. Also you don't have to split to multiple DVDs. They are bulkier than DVDs but not much nowadays.

    You might want to think about having two external disks that you take offsite in rotation.

    Hi

    I have been away and checked what ext3 and ext4 mean.

    I am going to go for ext3 (Random choice as I don't know much about it). I am going to partition the disk with 20 or 30 gb as fat32, so I can back up my children's machine which is running Windows XP.

    That will leave 130 gb for my machine. One last question should I partition that as well? Is there any chance that part of the disk will fail? So I will save something if I partition it or should I just leave it as one big partition?

    Thank you.

    i can't see any logical reason to not choose ext3..
    (ext4 is just barely out for non-beta use, in the last year..)

    hmmmm, i'm not a real file system guru and can't answer with cites...i
    can tell you what i would do--leave all the ext3 as one partition..

    yes, if that one partition table gets corrupted you are in for some
    work...but what is to say the same bug/hardware/firmware fault would
    corrupt only one of two or six partitions?

    in all answers: listen to ken_yap (especially if he and i disagree,
    i'm half way ok generalist...but, he is smart and has Linux experience
    far beyond my own..)

    I installed 11.2 with ext4. Would you advise the use of ext3 on an external HD for backups?
