Increments way to large

Thread needs solution

Hi, my first full backup is 500 GB, but every Increment is 70 GB. I also have tuned my Workstation for smaller Increments Backups (no pagefiles, disabled Windows search etc.).

 

What is the Problem here? Why there are such big increments if I only do some Outlook and Excel work per day???

Christian, welcome to these user forums.

Sorry but we have too little information here to be able to give you any answer other than pure guesswork.

What version of Windows are you using, what version & build of Acronis True Image, what types of backups are you creating, what exclusions are set for the backups?

One cause of larger backups can be if you have any programs doing any form of disk defragmentation, as Acronis tends to identify changed data at a sector level and defragmentation changes lots of sectors.

See also the MVP Log Viewer which can help you look at the logs created for your backup tasks by ATIH 2015 and later where there is no obvious means of checking the logs.  Link is in my signature below.

Hi,

  • I have Win 10 Pro x64
  • TrueImage v18.0 2015 Built 6613
  • Incremental daily, full after 2 weeks
  • Windows Indexing disabled
  • Windows defragmentation (on SSDs its calld optimization) disabled
  • default excludes +pagefile.sys +hiberfil.sys +Cloud Directories (Dropbox etc.)
  • Outlook ost's only 6 GB

But still 70 GB daily. MVP Log appended.

 

WTF is my system doing?

Christian, thanks for the log file information.

The key information that I see is that you are doing an 'Entire PC' backup which includes the following partitions.

id=18;  level=1;  module=1;  code=503;  date/time=24.04.2017 22:30:05
          message=Analysiere Volume '0-0'...
id=19;  level=1;  module=1;  code=503;  date/time=24.04.2017 22:30:05
          message=Analysiere Volume '1-1'...
id=20;  level=1;  module=1;  code=503;  date/time=24.04.2017 22:30:05
          message=Analysiere Volume 'C:'...
id=21;  level=1;  module=1;  code=503;  date/time=24.04.2017 22:30:05
          message=Analysiere Volume 'Q:'...
id=22;  level=1;  module=1;  code=503;  date/time=24.04.2017 22:30:05
          message=Analysiere Volume '1-4'...

The next step would be to mount your incremental backup image file as drive letters and see what the sizes shown for these partitions is?  Perhaps do the same for the original full backup image of this set, and compare those sizes.

The log does not show any errors and isn't suggesting that Acronis is switching to doing a sector-by-sector type backup which would cause the backup to be much larger.

Hi,

 

my research shows i cannot convert TI 2015 Images to VHD. How can I mount the tib?

Can I really mount the file and see all partitions and its sizes then?

 

Nevertheless, I am 90% sure, that Drive C: is the big one. Would be nice to finde the files that are responsible for that.

Christian, to mount the file, locate it in File Explorer, right-click and then select Acronis True Image > Mount which will then mount the partitions included in the image to drive letters.  Note: this is in read only mode.

Wow. Never thaught this can be that easy :-)

Unforunately I got an error Message thet the Backup-Archive-Navigator couldn't be initialized, I should reinstall TI 2015 (0x6400F8) :-/

Nevertheless I can expand the Images in Windows Explorer and see many "Full Backups" then. I can take a look, but I get no chance to see the properties and size of directories. And all Backups seem to have ALL files in it. Maybe only empty files as placeholders but I was not able to check what exactly was backed up last night.

I am having a similar problem.

Differential backups are now about the same size as the full backup at the start of the chain.  Way too large.

Using Win7, OCZ  1TB SSD and Acronis 2015.  Backing up to an external HDD.

Previously had worked fine.

David, differential backups will grow in size over time, especially if these are disk & partitions backups and there are regular updates to the OS etc.

Backup sizes will also increase if any defragmentation of the source drive is performed as Acronis looks for changes at a sector level, rather than just on a file or folder level.

I would suggest mounting you latest differential backup image to a drive letter then using a tool such as TreeSize Free to see where the greatest size of data is being shown - this may help to give you an idea of why the size has grown.

I would recommend starting a new full backup version chain if you want to get the size of differentials reduced again.

Thanks Steve,

I am using a series of external HDDs, labelled with separate drive letters and previously this method worked fine.

As an example,  A full backup taken on March 5th was 287GB, the first differential on April 17th was over 284.7GB, would expect it to be a max of 20-30GB from previous long term usage.  This has occurred repeatedly on other external drives.

Will use Treesize to get an idea of where growth is occurring and get back to you.

Thanks again David
