Good evening, I have been successfully using the backup-test-percentage for a little while and it’s been working perfectly fine.
I picked 4% for a backup that happens every 2 weeks, which means that roughly the equivalent in volume of almost everything should be checked over a year.
4% x 52 weeks per year / 2-week backup = 104% equivalent per year
One thing though is that I cannot find anything that discusses how the blocks are selected every time the backup is done. Would anyone know? I’m assuming it’s pseudo-random, not sequential, which means that technically not all data would be checked.
