@schily Using a committee-standardized format isn't the only relevant criterion for judging the quality of a backup program. DAR's format is openly specified. I don't understand what you want to get at with your question. Such a number would be hard to quantify for any backup program. I don't see how GNU tar is relevant here. For example, star advertises compression support but last time I checked it failed reporting errors when compression was enabled during archive creation.

| May 12, 2020 at 8:02 | comment | added | schily | I would not recommend DAR, since DAR uses a nonstandard archive format. Also, are there a sufficient number of successful incremental restores to verify usability? Note that GNU tar advertizes to support incremental backups since 1992, but still fails to restore non-trivial deltas. | |
| May 20, 2017 at 4:28 | comment | added | ayvango | DAR has inconvenient restoration procedure: each incremental backup physically overrides files from previous step. So, if your file changes 7 times, it would be extracted 7 times, and 6 copies would be wasted, overridden by the 7th. | |
