Question

linux

And what is the most reliable file system for Linux today?
Interested in the context of cold archiving to a hard drive.

Answer 1

Probably ext4, as the most mainstream, with which about 80% of users work. In second place, probably xfs, then everything else. For recovery, in which case, I would choose vfat, since you can read it, in which case you can anywhere, and store the data in tar format, which spits on corrupted pieces of your archive.
Putting it all together: VFAT + tar.

Answer 2

for cold archiving, any will be reliable

Answer 3

you need raid 1, and what fs will be there, the main thing is to monitor the state of the screws in the raid and that the raid would work fine

Answer 4

ext4 + default settings.
Of course, raid1 is still needed - a disk with a backup can simply die.
