BRiT Posted August 2, 2018 Share Posted August 2, 2018 chattr +i for files I don't want to ever change, like all my media files. Quote Link to comment
crossix Posted August 2, 2018 Author Share Posted August 2, 2018 that will not work for me, im planning of using for a server that needs constant access to it for writing/reading! Quote Link to comment
JorgeB Posted August 4, 2018 Share Posted August 4, 2018 You can use btrfs and regularly snapshot all the disks. Quote Link to comment
BRiT Posted August 4, 2018 Share Posted August 4, 2018 If you dont use btrfs with snapshots then you use your own snapshotted backups (via rsync or some other means) those should be chattr +i to make them immutable after the backups are done. A raid array is NOT a replacement for BackUps. You may need to rethink your setups. 1 Quote Link to comment

crossix Posted August 4, 2018 Author Share Posted August 4, 2018 Is btrfs "stable" enough, people saying you need ups backup for the server, cuz files tend to get corrupted for accidental shutdowns! and yes what is chattr+i? Quote Link to comment
BRiT Posted August 4, 2018 Share Posted August 4, 2018 "chattr +i" can be done on files or directories. That combo sets the item as immutable, meaning no changes can be done unless you "chattr -i" the items. It protects beyond "chmod 444". This was talked about in the ransomeware resistence thread(s). I assume everyone would have read that thread already before asking questions. Quote Link to comment

IMO yes, but like brit mentioned snapshots increase your protection against e.g. ransomware or accidental deleted/modified files but, and the same as unRAID, are not a backup, you need to have a backup of your irreplaceable files.
