First my recently installed version 10 build 4942, and now version 11 build 8027, are too slow to be useful. The archive creation is slow but the time required for backup verification/validation is ridiculous. I left the priority set at "low:. It took 1.5 hours to create a 46 GB backup with version 10. The verification/validation took 11.5 hours. It took 2.5 hours to create a 50 GB backup with version 11. The estimate for the backup validation stood at 17 DAYS when I cancelled it. Why does Acronis use two terms for the same thing: "validation" and "verification" - poor technical writing. Acronis should pick one and stick to it. The log doesn't give the name of the backup archive being created although version 11 seems to give its name as part of the line "Backup Archive Validation Location". Version 10 only gave me the folder name. I am running Win XP Pro SP2 with two switches between my computer (CPU: E6400) and my network disk, a D-Link DNS-323. I had heard good things about Acronis s/w. I am disappointed. The biggest problem is that if one can't trust ones backup s/w then it is useless. I cannot trust Acronis s/w at this point.
