Setup: My Windows XP desktop computer has two partitions, C and D. These two partitions are backed up weekly to an external (USB) Seagate “Free Agent” 500GB Drive using Paragon Backup & Recovery™, version 10.1.19.15786 (28.05.12 ) Free. The Seagate Backup Drive has two partitions named Free Agent #1 and Free Agent #2. These two partitions are the same size, (250GB) half of the 500 GB each. Procedure: Weekly, I backup the Desktop machine’s C & D partitions to either the Fee Agent partition #1 or #2 alternating each week. Results: It take only 121 minutes to backup to Free Agent’s #2 partition and 225 minutes to Free Agent’s #1 partition ? It creates the same 75 files having the same overall (145GB) byte count on both partitions. It just takes almost twice as much time every other week. Concern: Is there any logical reason that this timing discrepancy might occur or should I be suspect of the backup’s validity? Thanks for any insights you can offer in advance.
