Backup taking excessive time (and might not be working)

Thread needs solution

I have a 1 TB Samsung SSD for drive C. I also have four Western Digital hard disks in the computer that I backup to every Saturday. Typically my backups take a little more than an hour complete. Today I did my normal backup to the first three drives and indeed it took about one hour and 5 minutes to complete on the first three drives. I started a backup to the fourth drive and was surprised to the the time remaining to be three hours and 45 minutes. After about 10 minutes it increased to five hours and 38 minutes. Eventually the time remaining increased to over eight hours. The progress bar seems to be stuck at about 3 percent (i.e. 97 percent to go) and does not appear to be moving.

I stopped the backup and checked the drive being backed up to (G) and everything seemed normal. I ran a CHKDSK on it and all returned ok. I deleted the previous backup on the drive and tried again. Same problem. I then ran a CHKDSK of drive C and that returned no problems. I rebooted the computer and tried again, same problem.

I ran the Samsung Disk Magician utility to check the SSD and all seems normal. I am hesitant to try backing up again to the previous drives that were backed up to with no problem.

I am not sure what is going on here. I would suspect the Western Digital HD that I am backing up to has some kind of a problem but it seems to be passing any checks that I throw at it.

Recheck the task configuration on the extended backup.
Perhaps you have accidentally included some of the backup disks as to what is being backed up so your backup may accidentally be of multiple disks.

Hi Grover

"Task Configuration"?, "Extended Backup"?, do you mean the "settings" for the backup? I don't see a Task Configuration or Extended backup selection. I just stopped the backup when it said 10 hours to go. Maybe I should delete the backup task and recreate it? It backed up last Saturday with no problem. I only made a very minor change to the files on Drive C which resulted in adding about 10 Mb to the system so the backup should have been only a tiny bit larger which shows 286 Gb on the other drives that I backed up to earlier today and the 286 Gb would be exactly correct.

If your projected size for the backup is correct, then you can ignore my comments as they would not apply.
I would just start a new backup task pointing to a different storage folder.

Well, I tried deleting the task and recreated it and now the "Calculating" never goes away and no backup starts. I am really hesitant to try backing up to one of the other drives that backed up ok earlier today. I ran a chkdsk again on drive C with no errors. Also ran chkdsk on the HDD in question, no problems found. I ran several things on drive C (It is a dedicated flight simulator computer) and everything ran flawlessly so I don't suspect any corruption on Drive C.

Stumped. Still suspect the WD HD in drive G. I do have a portable drive that I can try backing up to prove the case. I'll try that tomorrow unless you have any better ideas in the meantime.

As always, i am very, very appreciative of your help.

Yes, backup to a different disk. If the same recurs, it would point to the source as the issue.

Hi Grover

Indeed it was the Western Digital HDD being backed up to dying a slow death. Last night I spent some time poking around on that drive. Some times it would give me an error when trying to copy a file, delete a folder etc. Other times it would let me copy and delete files ok. I tried to do a CHKDSK on it again and I got a "Permission denied" error. Going to disk management in control panel indeed would not allow me to work with the drive which I have never had a problem with that before. Things got worse as the evening progressed. On reboot and shutdown windows was taking a long time to perform normally. I finally removed the drive and all seems to be ok now, windows is starting and shutting down normally. I just ordered a replacement drive. It is now obvious the HDD was slowly killing itself.

Thanks again for your assistance.
