OK, I have NO idea what has happened?
First, before anyone asks,
- SAME PC!
- No H/W changes.
- No Backup source major changes, maybe some files removed, others added.
- Win10 Pro Ver Build 19043.1081, all the latest fixes.
- USB drive, is a WD MyBook 4TB drive. It is a USB 3.0 drive, but the port appears to be operating @ USB 2.10 (possible h/w problem).
- PC was in use some of the time the backup was being done. Same for all prior backups.
Folder where the backups are stored:
Volume in drive N is My Book
Volume Serial Number is 1A5E-C890
Directory of N:\Acronis_Backup

2 Dir(s) 1,559,111,843,840 bytes free
Note the file sizes on the last 2 backups. 6/17 was actually done 'twice'. Files were removed (as the size differences reflect) and after the removal, another backup was done manually. Others are kicked off on schedule.
Now the last TWO backups logs.
I can not fathom the TIME differences? Less than 4 hours? No, that 14+ hours is basically normal. All others are in the 12 to 16 hour range. I assume due to file changes and what is going on on the PC while the back-up is going on?
Not the USB port either. At one time the port did support USB 3.0 and I don't know why it changed, but buck-ups were about 5 or 6 hours then.
Checked the file out, and it appears to be good:
I drilled down into the folders and all data appears to be there of those I sampled?
A compare of the back-up and the disk of a random folder:
I am at a loss to explain this?
