# Rock-stable filesystem for huge documents (back-ups) for linux

What filesystem would certainly be best for back-ups? I'm interested key in security (specifically uncorruptability of documents throughout tough reboots and so on) yet just how successfully it takes care of huge (> 5GB) documents is additionally vital.

Additionally, which place parameters should I make use of?

Bit is Linux >= 2.6.34.

MODIFY: I do not desire backup approaches. I require the filesystem to store them.

btrfs has clear checksumming of information contacted disk and also a rapid ordered-writes setting that is constantly on (and also several various other backup-friendly attributes) that makes it appealing for back-ups. See https://btrfs.wiki.kernel.org/index.php/Main_Page for even more information.

Just make use of a backup device that sustain checksums. As an example Dar does, and also it sustains step-by-step back-ups. After that you can backup to an unfailing filesystem like ext3.

For back-ups you desire something rock solid/very secure. And also btrfs or ZFS are merely not all set today.

XFS is unfailing and also has actually remained in the bit for ages. Check out devices like xfs_freeze and also see if it is what you are seeking. I recognize this is very subjective yet I have actually made use of XFS for information storage space for several years without case.

You can make use of ext4 yet I would certainly advise placing with journal_data setting which will certainly switch off dealloc (postponed appropriation) which 'cause d some earlier troubles. The disabling of dealloc will certainly make new information creates slower, yet make creates in the occasion of power failing much less most likely to have loss. I need to additionally state that you can disable dealloc without making use of journal_data which has a few other advantages (or at the very least it carried out in ext3), such as a little boosted reviews, and also I think far better recuperation.

Levels will certainly still aid with fragmentation. Levels make delete's of huge documents much faster than ext3, a delete of any kind of sized information (file) need to be near rapid on ext4 yet can take a long period of time on ext3. (any kind of level based FS has this benefit)

ext4 additionally fsck's faster than ext3.

One last note, there were bugfixes in ext4 up to such as 2.6.31? I would primarily see to it you aren't running a bit pre 2.6.32 which is an LTS bit.
