Create system image utility - some general questions
I normally use Acronis True Image for backup and recovery. Fine for file and folder recovery, but I want a reliable full system image of the Windows 7 PCs before upgrading to Window 10. I've just discovered that the Acronis bootable recovery system could not read always my backups so I'm trying the Windows Backup and Restore utility.
For some reason I get an I/O error when backing up to a Western Data 3 TB USB 3 external drive. (Interestingly Acronis writes to the disk with no problem, and, after a few false starts, the recovery system has no problem reading it.) Before I research this more, is there any reason the Windows Backup and Restore utility would have trouble creating a system image backup on a 3 TB USB 3 external drive?
The backup seems to be working fine to an old Seagate 2 TB USB 2 external drive. Is there any way to verify the backup once it is created? The Acronis recovery system had trouble reading backup fines on this disk even though Windows (and Acronis TI 2015 running on Windows) had no trouble reading and writing. I want to make sure the Microsoft recovery system does not have the same problem. But I don't want to do an actual recovery just to validate the backup.
And finally, Process Explorer shows no disk I/O even though the backup seems to be progressing (slowly). Is this I/O somehow hidden. My Kaspersky security software does show I/O activity.
