I upgraded tar on two linux servers that I use for backup and restore. My dataset is 2.2 TB and I noticed the following (significant) difference
tar-1.15-1: Backup: 36.373 hours @ 16.5 MB/hour Restore: 57.067 hours @ 10.5 MB/hour tar-1.20: Backup: 37.88 hours @ 16.0 MB/hour Restore: 142.98 hours @ 4.2 MB/hour The backup times are close enough, my problem is with the restore time; an increase of 250%. The only thing changed on my system was the version of tar. If this is not a know issue, or a unique occurence in my case, I could run 1.20 for backup and 1.15.1 for restore, but I don't really want to have two differnt versions installed. Am I missing something? - Jaco van der Schyff
