Thanks for your reply .I dont use windows anymore, yet I tried to "share" my archive with a winXP PC via samba while formatted in ext4 and I could read my archive without problems.
Would ext3 be safer than ext4? From what I know ext4 main advantage is better allocation and less fragmentation ( which is not imporant for me since my flash is 8GB)
Regarding safety ext4 does checksuming allowing for better reliability which I find very important but delayed allocation frightens me somewhat. I always have backup via rsync but what if, say, I change one of my files and then system crashes? how delayed is delayed allocation namely what is the expected time for the data (not the metadata) to be written in ext4 systems?
And if I rsync my archive wont the corrupted file overwrite the one in my backup ?
