Macrium Reflect very slow differential backup but very fast verify
Hi,
So today I tried to use Macrium for the first time.
I first made a full windows restore backup that took 56mins to finish and right after that made a Differential image that took 41mins to finish.
The full backup files size is 113gb and the differential backup file size is 1,7gb.
How is it that the differential backup took almost as much time as the full backup to finish even though the file size is that much different.
Also, as the titles says, when macrium verified the differential bckp image it took only 30s to complete when for the full backup image it took about the same time to verify it than to make it.
I am using a WD Elements external HDD to store the backups, plugged-in trough a USB3.0 port and the reported data rates for full and differential are respectively "Read 2.0 Gb/s - Write 598.5 Mb/s" and "Read 1.5 Gb/s - Write 495.8 Mb/s"
Thanks in advance for any help.
