ATI 2017 broken by Windows 10 latest update?

Thread needs solution

I have set my 4 notebooks to run ATI Partition backups automatically overnight, as has been done for many years.
over the last few days I noticed that the back-up jobs were not completing and found from the email logs
that the allocated times before close down were not enough. Now using ATI 2017. The notebooks (all running Win 10)
are various ages ranging from 10 to 2 years old and are a mix of Dell and HP.

When running several of the jobs manually, I found that there was significant corruption somewhere that caused,
for instance a "C" partion of 930GB, holding 129Gb of data, was suddenly being reported by ATI 2017 as having 4.4TB
to back up, and proceeded to do that, with an estimated time of 1d 22h. Needless to say, I killed the job after 1TB,
which is of course in excess of the physical maximum of 930GB, as well as way over the actual data of 129GB.

As a test on one notebook, I restored back to a ATI 2016 version, ran the Win 10 updates, and the problem was recreated, so updated to  ATI 2017,
removed the saved backups and recreated the backups. As a test, I UNTICKED Sector by Sector backups, which I have always used for Partion backups, Problem solved!!

As part of my backups, I run a daily backup of my documents only. It is interesting to note that this File/Folder backup did not
appear to be affected. As an example one notebook was creating an ATI file of 1.1GB each day and that amount did not change with the
"growth" in Partition backups. However, the reported size (when running the backup), has grown each day it has been run.
For the past 3 days, the reported backup size within ATI has gone from 1.1GB (usual size) to 2.2GB the next day and the third day
it was run is now showing 3.2GB reported size. It should be noted that actual ATI backup file size has not changed significantly,
only with the addition of new documents, so it would appear that some corruption still exists.

I then examined the recent history of changes to all the notebooks, and found that the only changes were the Microsoft updates for
28 Oct 2016 (Western Australian date & time)

All notebooks were checked and no virus/malware was found, which is not surprising as all notebooks are updated/checked maually
twice a week as well as their resident components running continuously.
All notebooks are now running ATI 2017 with freshly created backup jobs(not using Sector by Sector), all the latest Win 10 updates and are all running ATI 2017 smoothly, apart from the File/Folder problem mentioned earlier.

It seems that there has been some interaction between the latest Win 10 updates and Acronis 2017.

It would be great to know the real cause of this problem, rather than relying on workarounds.
Thanks Ross

I think the issue is not with Microsoft compatibility but the sector by sector setting.  Sector by sector is disk/parition only backup option and will cause Acronis to backup the entire disk - including the blank/unused space - essentially the backup will be the size of the actual hard drive (minus a little difference due to compression).  No matter what settings you have, if sector by sector is enabled, that's what you're going to get. I would recommend only using sector by sector if you have a known bad/corrupted drive and that is the only way you can get through a backup.

So part of the issue could be from the original sector by sector setting.  If you are also setting up your backups using "entire pc" instead of disk/parition, that could be another cause.  Entire PC is designed to backup any internal drives (and sometimes grabs external ones too - especially if they are eSATA).  So, instead of just backing up the main drive, you may be backing up much more if you have multiple disks attached.

And if the backup size says it's still that large after removing the sectoro-by-sector setting and you have verified what your "entire pc" backup is including (I'd recommend not using entire pc and do  a disk backup instead though), then it could be corruption on your source disk.  If corruption is found and Acronis can't get past it, it may default to sector by sector automatically.  You can run a chkdsk /F on the source drive and see if any issue are found.  If there are, you should do a chkdsk /R . Be prepared gto let these run for quite some time if you have a large disk...

CHKDSK [volume[[path]filename]]] [/F] [/V] [/R] [/X] [/I] [/C] [/L[:size]] [/B]

  volume          Specifies the drive letter (followed by a colon),
                  mount point, or volume name.
  filename        FAT/FAT32 only: Specifies the files to check for fragmentation.
  /F              Fixes errors on the disk.
  /V              On FAT/FAT32: Displays the full path and name of every file
                  on the disk.
                  On NTFS: Displays cleanup messages if any.
  /R              Locates bad sectors and recovers readable information
                  (implies /F).
  /L:size         NTFS only:  Changes the log file size to the specified number
                  of kilobytes.  If size is not specified, displays current
                  size.
  /X              Forces the volume to dismount first if necessary.
                  All opened handles to the volume would then be invalid
                  (implies /F).
  /I              NTFS only: Performs a less vigorous check of index entries.
  /C              NTFS only: Skips checking of cycles within the folder
                  structure.
  /B              NTFS only: Re-evaluates bad clusters on the volume
                  (implies /R)

The /I or /C switch reduces the amount of time required to run Chkdsk by
skipping certain checks of the volume.

 

As for the growing file sizes each day, that is pretty normal depending on what data is changing and what you're excluding or not.  For instance, an Outlook PST that is is 2Gb will backup 2Gb every day because it's one file that changes anytime you open the .pst.  If you've removed all of the default exclusions, you choudl be backing up the pagefile each day (which is a waste of backup space).  If you connect an iPhone and iTunes backups your phone every day, then Acronis will backup that backup.  And, are you using differential or incremental backups?  Incremetnals backup the changes since the last backup before it.  Differentials backup all changes since the last FULL backup so differentials tend to be larger with each new differential that is taken until the next full is completed and the diffs start over again.
