I vaguely recall using it a long time > ago. You could also use dump, if you want to archive a whole filesystem. Dump can write to multiple volumes, it handles everything in a Unix filesystem, and it's fast. For multiple volumes, it would write directly to the device, without filesystems. If your memory sticks are larger than FAT can handle, you could put some other filesystem on them, like UFS. I believe FAT32 limits a single file to 2 GB. It's also slow.
