- There was a comment about LoneTar being junk. There are three very closely
- related companies, LoneStar, Cactus International, and UniTrends. They
- offer almost identical products except that UniTrends offers CTar, rather
- than LoneTar. CTar offers a "ctar -t" option, just like tar -t, and ctar
- -T, where the UpperCase causes a true compare. After a full backup, the -T
- option tells me that /etc/utmp is a different size, and that /etc/wtmp
- failed to compare (or vice versa).
- I might be wrong, but I trust that the backup has completed successfully,
- and that all of my data matches.
- tar -t, or cpio -it is better than nothing, but it doesn't guarantee a good
- backup, just a readable tape.
