Daily Incremental Backups used to be small, now massive

Thread needs solution

Hi - I have been doing daily TI-2017 incremental backups of my PC's main hard drive for years.

I recently had to restore my hard drive after a disk corruption issue. The restore mostly came out fine - I needed to mark my main partition as "Active", and then my system was operating OK again.

One bad thing that has occurred after the restore which is causing me a lot of grief, though.

Previously, my nightly backups were about 2 GB or less of data (until the next full backup every 14 days on my settings). This worked out fine - I also do PC image backups to the "cloud" every night.

After my restore, my nightly backups are now 25 to 35 GB each ... which means that I will blow through my monthly ISP data allotment well before the end of my cycle.

Is there a fix for this? How can I identify why my incremental backups started getting so huge?

Thanks,

Alan

Am I correct that you are backing up to Acronis Cloud - I infer this from the reference to you ISP data allotment.

If you had a data corruption issue then this may explain what you are seeing. If ATI see a major issue with the disk being backed-up it does a sector by sector backup, which is a full backup. The first thing I would do is to download the HDD/SSD manufactures disk utilities and run them to make sure there is not a significant problem; in particular the HDD/SSD may be failing. You may have to replace the disk; relatively easy for most desktops but can be a challenge with some notebooks, particularly the ultra slim ones.

Just a thought, but I have resolved occassional backup runaway file sizes by running chkdsk c: /f /r

Thanks for the suggestion, satwar - I suspect you are right. I did find multiple errors when I ran a chkdsk. That's the good news.

The bad news is that I found so many drive errors, I can't trust the integrity of my SSD drive any more (though it seems to work fine).

I think I will go back to a previous TI-2017 backup, and try to restore, and bring all my current documents over from last night's image.

I will let you know how it goes!

Alan, please check with your SSD drive makers support website for any diagnostic utlities for checking the drive, i.e. such as the Samsung Magician program for their SSD drives.
