Error While Configuring Disk Image Backup - "Error Creating Snapshot EVSSException SGException”

Error While Configuring Disk Image Backup - "Error Creating Snapshot EVSSException SGException”

KB ID: 61
Cause:
This error occurs when configuring a disk image backup, and BDRSuite encounters an issue creating a snapshot, resulting in the error message "Error Creating Snapshot EVSSException SGException.”
Solution:
During a backup, Volume Shadow Copy Service (VSS) creates a volume shadow copy to facilitate the transfer of data to the backup server. Sufficient free space on the disk is required to store the data for the volume shadow copy.
Follow these steps to address the issue:
1. Free Up Disk Space:
  1. Ensure that the volume where the backup is being configured has adequate free space.
  2. For volumes less than 500 megabytes, a minimum of 50 megabytes of free space is required.
  3. For volumes more than 500 megabytes, a minimum of 320 megabytes of free space is necessary.
  4. It is recommended to have at least 1 gigabyte of free disk space available on each volume if the volume size is more than 1 gigabyte.
2. Check Shadow Storage Configuration:
  1. Run the command: `vssadmin list shadowstorage`
  2. Pay attention to the value of "Maximum shadow copy storage space."
By ensuring sufficient free space on the volumes and understanding the shadow storage configuration, you can resolve the "Error Creating Snapshot EVSSException SGException” issue during disk image backup configuration.
