What are the options for saving backup information, as a file system parameter, and which file systems have this option?

Question

File systems

You need to find out which file systems from the list have the ability to save backup information and which do not:
- FAT32
- ext2\3\4
- nfs
- swaps
- ufs
- reiser fs \ reiser 4
- hfs \ hfs+
- ntfs
- BTRFS
- jfs

Answer 1

I think we are talking about shadow copies.
ntfs, btrfs, zfs can do this
. Also on Linux, you can do this everywhere through LMV.
But shadow copies are not the kind of backup information that can replace backups.

Answer 2

What is your understanding of "backup information"?
