Backup size

Thread needs solution

On previous PCs my backup files were usually slightly smaller than the original. However on my new Win 11 PC I am backing up my C drive which has 2.6TB. However the backup at around 80% run is already at 3.3TB and will probably fail as too big for my 4TB disk. Sent in a ticket but has anyone else seen this?

Chris, the most likely reason for the very large backup size is that there are some file system issues on your C: drive that is causing Acronis to switch to using sector-by-sector mode which in turn can result in a backup file of similar size to the whole disk.

Check the backup logs to see if it reports any errors and try running CHKDSK C: /F or any diagnostic utilities provided by the drive maker.

Download a copy of the MVP Assistant log viewer tool and use this to look at the logs to see if they show any issues during the operation process?

The latest version of the new log viewer tool is at the link below.
MVP Assistant - New 2.0 with Rescue Media Builder (New Version 2.7.5.1)

If you have Disks & Partitions backups created on ATI 2020 or later using .tibx files, then look in the Backup Worker logs.

If you have Files & Folders backups using .tib files (or Disk backups from earlier versions using .tib files) or using Cloning then look in the Demon logs.

Other logs are shown by the MVP Assistant under the 'Active Logs' heading of the Log Viewer page of the Assistant, i.e. Media Builder.

The Schedule2 log contains information related to scheduled task but is one of the more difficult logs to read / work through.

The log files should be zipped to preserve their original file names if sharing in the forums and would need to be less than 3MB in size, otherwise you would need to share the zip file via a Cloud share service such as OneDrive, Dropbox etc.
