Ok, the first rsync full backup (488) completed. It took 500min. longer than
the last tar full backup (482).
Backup Type Filled Level Start Date Duration/mins Age/days
482 full yes 0 5/19 02:05 3223.2 11.5
483 incr no 1 5/21 07:49 89.6 9.2
484 incr no 2 5/22 03:05 136.4 8.4
485 incr no 3 5/23 03:05 119.1 7.4
486 incr no 4 5/24 03:05 111.4 6.4
487 incr no 1 5/25 03:05 165.9 5.4
488 full yes 0 5/26 21:00 3744.2 3.7
489 incr no 1 5/29 12:15 394.1 1.1
490 incr no 2 5/30 03:05 190.8 0.4
I'm not sure if the checksum caching will compensate this in after the 3rd
backup. Anything else I could do to tune rsync?
