I think this would answer you question:

From FAQ: http://www.fsarchiver.org/FAQ
FSArchiver 0.1.5 is able to save/restore all linux file-systems (ext2, ext3, ext4, reiserfs, reiser4, xfs, jfs, btrfs), but at the moment only ext2/ext3 and reiserfs have a specific file-system attributes support. It means if you save an ext3fs, your file-system label/uuid will be preserved when you restore, but if you use an xfs, the file-system attributes won't be preserved. The contents of the file-system (files & directories) must be ok on an xfs anyway, including the file attributes (permissions, atime/mtime, ...). We are focused on implementing a good support for ext2/ext3/ext4 and reiserfs first, since these file-systems are widely used, and we will work on the file-system attributes for xfs, jfs, reiser4, btrfs as soon as we have time to do it.


Since version 0.1.5 here is the changelog:

# 0.1.9 (2008-12-23):

* Bug fix: it was not possible to restore an ext{2,3,4} partition if it was mounted read/write during the savefs
* Bug fix: opening an archive may fail in restfs for no reason
* Thanks to 666Setsuna666 for these bug reports

# 0.1.8 (2008-12-07):

* Preservation of the reiser4 filesystem attributes (label, uuid, block-size)
* Preservation of the jfs filesystem attributes (label, uuid)

# 0.1.7 (2008-12-07):

* Preservation of the xfs filesystem attributes (label, uuid, block-size)

# 0.1.6 (2008-12-02):

* Preservation of the ext2/ext3/ext4 filesystem-features and default mount-options

# 0.1.5 (2008-11-30):

* Fixed bugs related to the standard and extended attributes

No, FAT is not supported at all.

Could you please add support for FAT/FAT32?
It will be very useful to backup flash-drives.

It's possible to implement fat. One problem is that it will be very difficult not to break a bootable fat partition with windows installed on it.

No you cannot save a squashfs, and it does not really make sense to do that

If this is still so, then this statement on the FSArchiver home page is not accurate:
"FSArchiver is working at the file level. It can make an archive of any file-system (ext3, ext4, reiserfs, xfs, ntfs, ...) that the running kernel can mount with a read-write support."

fsarchiver is a great tool, and I'd love to be able to use it for all my drives, including any FAT ones.

What's the plans for FAT support, is it even on the to-do list?

As said earlier, there is no plan to support FAT yet since it's difficult to preserve the ability to boot on such a partition. So people would complain that their Windows cannot boot from a restored partition if support for FAT was implemented.

Ok, thanks for the update.

I had read in another thread that you may consider FAT support if you had more info, but I guess that's not an option (yet?).

If someone can find the exact steps to make a fat partition bootable that I can implement quickly, why not.
The question is what data have to be written in which sectors to make the fat partition bootable once it has all original files. Recent Windows versions such as XP can be installed on FAT filesystems so it's possible to test with that.

fsarchiver will achieve the equivalent of a standard file copy to a recently formatted fat partition. So there are extra things to do.
If you read "man mkdosfs" you can see this:
mkdosfs can not create boot-able file systems. This isn’t as easy as you might think at first glance for various reasons and has been discussed a lot already.
