What's with the values?

Thread needs solution

When I backed up this afternoon I noticed the values for the Source make no sense.  It seemed to be saying the  size was 415.5 GB when the entire drive is only 250 GB.  See screen capture below.

Make sure you have selected the partitions you want, and nothing else.

 

Can you post a screenshot of the Windows Disk Management console?

It is possible that the NTFS information of your disk is corrupted. Run Chkdsk X: on each X: partition of the disk.

 

"entire pc" backups may backup more than a single drive - it's in the name.  You want to be doing a "disks and paritions" backup if the intention is to only backup a single disk and all paritions.

Also, The total size of the backup shown is the total of all backups in the backup chain... full + the additional incrementals or differentials.

I don't know how to run ChkDsk on the small partitions that came on the disk, from Lenovo.  I ran the extended ChkDsk on the Win 8 partition.

I only do full backups

JIm, mine is reporting the total size of all backups in that Windows folder as related to that task.  This includes all versions of fulls and differentials, so I'm assuming you have more than one full in that location at this point. Check the properties of your backup folder in Windows (I'm aslso assuming you are using one folder per backup as is the recommended method).  The total size in Windows properties should report what is being shown in Acronis. 

I don't think I understand.  What do you mean by "that Windows folder"? 

Isn't it supposed to be reporting the amount to be backed up?  That is, the amount in the source, not the amount in the backup.  The amount to be backed up from the source is about 206 GB. 

There were no backups when I began this backup so the amount of backup data in the target drive would be zero. 

The total amount of used space on all three of my drives is 590 GB, the total used space on my two internal drives is 406 GB.

By " I'm aslso assuming you are using one folder per backup as is the recommended method" do you mean I should put the backup image file in a folder?  I put it in the root directory of my backup drive.

It's reporting the size of all backup associated with that task.  Hence if you have 3 full backups of 100GB each - it will show 300GB total size for that backup.  Go to Windows Explorer (My Computer)... navigate to the folder where your backup is located.  Right click on the folder and select "properties"  The size that Windows shows, assuming that folder only has the backups for that task, should be the same size as the total of all backups in that backup task.

Yes, I would recommend that you keep each backup tasks outupu in it's own folder.  The reason being that many people re-use backup names for their backups.  If you have such a scenario at any time, and there are old backups with the same name in the same folder, you're likely to see database corruption... not corruption of those backups, but Acronis is likely to have problems managing them since they all have the same name, but were not created with the same and active backup task with that name.    Keeping each backup task in it's own folder will avoid multiple backups being stored in one single place which can get messy... especially if some of those are older backups with the same name.  

I don't know how to make it any clearer than what I've said.

Neither do I.  Best of luck.
