2926: Mounting Several Partitions from One Backup Archive or One Partition to Several Directories in Read/Write Mode at the Same Time Corrupts Its Incremental Slice

use Google Translate

Avoid mounting in read/write mode several partitions from one backup archive at the same time in Linux. Also avoid mounting one partition to several directories at the same time in Linux. This will corrupt the incremental slices

This article applies to:

  • Acronis Backup & Recovery 10 Advanced Server (Agent for Linux)
  • Acronis Backup & Recovery 10 Server for Linux (Standalone)
  • Acronis Backup & Recovery 10 Advanced Server - Virtual Edition (Agent for Linux)

Symptoms

  1. In Linux, using Acronis Backup & Recovery 10 you mount in read/write mode several partitions from one backup archive at the same time. Or you mount in read/write mode one partition to several directories;
  2. You make some changes to one or all of the mounted partitions;
  3. After unmounting the palpitations the incremental slices to which the changes were written are corrupt.

Cause

Acronis Backup & Recovery 10 does not synchronize changes made to the same partition mounted to several directories simultaneously or changes made to different simultaneously mounted partitions from the same backup archive.

Solution

Avoid simultaneously mounting several partitions from the same backup archive or mounting one partition to several directories.

More information

In the latest build of Acronis Backup & Recovery 10 there is a limitation - you can mount only one partition at a time from the same backup archive in read/write mode; you cannot mount one partition to several directories simultaneously.
