That depends on many things.
How often do you backup and what do you backup....what do you expect to be able to restore should there be a major prob?
Win
Ix has well stated a separate page file partition, but that is only necessary for intense apps or old computers.
I never use ntfs, but I guess it's a good idea for most people.
I don't do the separate partition for program files anymore either. Too much hassle in repair, and you end up fixing things continually, til the next disaster.
The dual storage fat partition is also something I do, but it needs to be backed up regularly, incase of corruption, so I make several of these so making backups is quicker and easier.
Lin
Same.....what do you bkup, and what do expect to be able to fix?
I use reiserfs and have for years w/o any issues.
I no longer bother with diff /usr /tmp and /var. Time in making backups is much longer than just reinstalling. Preferences are in $HOME anyway, so I just back that up. If / is big enough then all is well.
