The best filesystem for a partition if data savety is important

I have a 100GB partition and don't know which filesystem is the best. Speed is not important because the linux system and /home are on other partitions, so the files are not accessed very often. Unfortunately making a 100GB backup with a dvd writer is not very comfortable. The loss of data after a forgotten unmounting (for example after a reset) should be as low as possible, also the linux 2.4 kernel should not have any problems with the filesystem. For example I've read that writing NTFS is not safe with linux.
Based on a message in this forum ( threadid=196935 ; I'm not allowed to post links within my first postings , no one told me so I needed to rewrite the whole message :-( ) I thing ResizerFS would be the right filesystem. Finally it would be nice if there are some driver for the filesystem for read access under Windows9x.
Is ResizerFS the right choice or exists there a better filesystem?
Thank you in advanced.

probably ext3. best documented, and the filesystem checking tools work well.

I'd personally go with ext3. Reiser is probably faster, but I think ext2 is more robust. There are other filesystems as well, but ext3 can be read by windows (at least at an ext2 level)...

I've used reiser for years without any problems. Recently I've been trying out xfs. I don't think there is a huge difference reliability-wise, any journaling fs will be OK, reiser/ext3/xfs.

However, no fs can protect you from hardware failure, you will still need to back it up, which is a whole other subject.

It may not be comfortable for you, but it's absolutely mandatory to backup if your data is at all important to you. No other way around it. Choosing a journeling filesystem with a proven track record is all well and good (I'd personally choose ext3 for that myself), but to leave it at that and consider yourself well protected is just pure folly.

For a minimal hassle and cost recommendation, I'd say buy yourself an external disk and backup to that. Make sure that disk is cleanly unmounted, totally disconnected, and stored off site (a bank safe-deposit box?) if you're even minorly serious about protecting your files. For really important irreplaceable data, you need multiple redundant backups stored in geographically diverse locations. And you need to practice and verify restores from these backups from time to time.

Is your data really important to you? If so, you just have to bite the bullet and do some "uncomfortable" stuff to protect yourself. There's no shortcut.
