Huge backup file and corrupt sectors?
Hello,
short question that bothers me for a long time: If I have a 6 TB harddrive and make a full backup, so that for example a 4 TB backup file will be created, what if one bad sector that can't be read appears in that single file that is 66% (4 TB) of my harddrive? Will the whole backup be currupted? That drive already has 31 pending sectors. There were a few single files in the past that can't be read and had to be replaced from other places.
Many thanks in advance for your reply,
Loam

But now, there is another problem. When I try to verify the previous succesful created backup file (3,7 TB) I get the following error:

After that my pc crashed with a bluescreen at the exact time, when the scedule for the incremental backup should start.

There is definatelly something wrong. Any ideas what could help?

As for 4102 error, where did you save the backup? Please try to browse and select the image file manually to check.
As for bad sectors, if the disk you want to back up has bad sectors, generally, AOMEI Backupper will skip the bad sectors to backup. That's to say, it doesn't back up the data in bad sectors.
So, here we go. As stated, the schedule for incremental backup works good now with the new version.
"As for 4102 error, where did you save the backup? Please try to browse and select the image file manually to check."
I can also open the backup files with windows explorer by double click and mount the three hard drives, browse them in explorer and copy files.
I have :
C : with system SSD on Windows 10
D : 6 TB harddrive for my files
E : also 6 TB as my backup drive
C and D are backed up on E as a full harddrive backup with daily incremental backups.
The hardware is:
C : Samsung SSD 840 EVO 1TB
D : Western Digital WD Red 6TB WD60EFRX
E : Western Digital WD Red 6TB WD60EFRX
If I click on tools-> verify backup, I still geht the error after about 5-10 minutes with 0% running the verification. It takes a bit longer with the first incremental backup after the full backup.
It's still the same error I get: https://imgur.com/6cl2BhZ
Thanks for your help!
Could you send us the log folder under the installation directory of AOMEI Backupper so that we check?
Yes, please check pm for the download link. Thanks
One more thing I noticed: The incremental backup takes extremely long. The last schedule was yesterday. Now another backup startet 1,5 hours ago and has 20%. Since the last incremental backup yesterday I did not really work on my computer, just browsing, mails etc. It is going to take around seven (!) hours again, like yesterday.
"The incremental backup takes extremely long."---Could you try to create two backup tasks to back up C and D Separately?Aftet that, please check if the incremental backup still takes a long time.
I did send it again (click on your name, click on message).
ok, I will try that. If one backup (schedule) is working on a backup and the next one wants to start, I guess it gets paused and put to queue.
It will take some time (4 TB). I start the incremental backup tomorrow morning and tell you about it.
Thanks!

There is definitely something going wrong. I am using backup software for ages and neither there should be read error when verified nor take seven hours for incremental backups for 4 TB. The ETA was around 10-40 minutes normally for an incremental backup. 7 hours is like making a full backup every time. We just need to figure out if it comes from a bug, my hardware or the way the backup works.
But besides that I understand your point. You suggest not to backup everything. The problem here is that I change files everywhere now and then. The time, as described above, would be the same. It doesn't matter if I backup 1x4 TB or 8x0,5 TB with single partitions. I don't really care about a full backup taking a long time but the incremental backup should be way faster. Also, it's so important to verify backups regularly to check for integrity. Maybe folder synchronization is faster. I will probably check that later but first wait for admin to reply.
And yes, maybe a huge file is a problem. That was my question from the first post. If sectors get faulty, maybe the whole file is corrupt? I don't know.
Yes, Google drive seems to have problems. The link was working before, dunno. E-mail should be ready.
Somehow I got an E-Mail from AOMEI first that I did reply with the logs attached. It's all good.
