I recently did a backup of a FAT32 disk which contained a lot of diverse data. It contains many media files, many big binary files, and as usual with FAT32, it has all kinds of odd (but potentially important) permissions for all of these different files. The whole directory of this backup weighs in at a few hundred GB. I would like to have a compressed archive of this backup, but I have a few requirements from whatever archival utility that I use:
- It needs to preserve extended attributes
- It needs to preserve timestamps
- It needs to preserve permissions
- I would like for it to preserve as much metadata as possible
I know that there are many different archiving utilities which fit at least some of my needs, but I would like to know of one which fits them all. I.e., which one can maintain the most metadata and also (preferably) has a good compression ratio for a diverse data set.
