Introduction

By default Acronis Cyber Backup creates cache of file system metadata of volumes backed up on tapes in the following folder:

Windows Vista/7/8/2008/2008 R2/2012: \ProgramData\Acronis\BackupAndRecovery\TapeLocation

Windows XP/2003: \Documents and Settings\All Users\Application Data\Acronis\BackupAndRecovery\TapeLocation

In Linux: /var/lib/Acronis/BackupAndRecovery/TapeLocation

This cache is required for cataloging, browsing and restoring files from disk archives located on tapes. Sometimes the large size of the cache might cause the system partition with low disk space to become full.

Below are instructions on how to move the cache location to a different folder.

Solution

On a Windows machine:

Use junction point to move the TapeLocation folder to another disk:

1. Invoke Windows Services (Start-Run -> services.msc) and stop all Acronis services.
2. On Acronis Cyber Protect 15, Self-protection must be temporarily disabled in order to stop Acronis services. 
3. Acronis Cyber Protect 15: how to disable self-protection

   Disable Self-Protection on the machine: 

   1. open the protection plan for editing,
   2. go to Active Protection module,
   3. turn off Self-protection,
   4. save and apply protection plan

   Move the folder TapeLocation to the new location, e.g. to D:\Acronis\TapeLocation

4. Verify that the TapeLocation folder does not exist in its original location at C:\ProgramData\Acronis\BackupAndRecovery\TapeLocation . Otherwise the creation of Directory Junction will fail due to name conflict.

5. Run cmd "as administrator" and execute the command:

   mklink /j C:\ProgramData\Acronis\BackupAndRecovery\TapeLocation <new_tape_location>

   e.g. mklink /j C:\ProgramData\Acronis\BackupAndRecovery\TapeLocation D:\Acronis\TapeLocation

6. Start Acronis services. If using Acronis Cyber Protect 15, re-enable Self-protection.

As a result, NTFS file system will forward all requests from the default TapeLocation to the new location.

 On a Linux machine:

You can use one of the following methods to change cache location:

• Place the new cache location on local disk:

  sudo mount /dev/sdb /var/lib/Acronis/BackupAndRecovery/TapeLocation

  Replace /dev/sdb with the necessary address

• Place the new cache in a folder on a different disk:

  First, mount the disk that you want to use for cache location
  sudo mount /dev/sdb /path/to/directory

  Then make a link to the specified directory:
  ln -s /path/to/directory /var/lib/Acronis/BackupAndRecovery/TapeLocation

  where /path/to/directory is the address for the new folder

• Mount a network share to serve as a new cache location:

  mount.cifs //host/share/folder  /var/lib/Acronis/BackupAndRecovery/TapeLocation -o user=useName

  mount -t cifs //host/share/folder  /var/lib/Acronis/BackupAndRecovery/TapeLocation -o user=useName,password=Password

By default Linux doesn't keep a volume mounted after reboot, so it is recommended to modify /etc/fstab to make the mount permanent. 

Under Linux-based bootable media

1. Press Ctrl+Shift+F2 to open shell
2. Specify cache location using one of the methods described in On a Linux machine section above
3. Press Alt+F1 to return to bootable media user interface
4. Rescan the tapes: see product documentation for instructions

(!) Due to the large size of TapeLocation folder, RAM size may not be enough to mount it in case of recovery via bootable media; in this case TapeLocation need to be re-mounted on a network share or mounted drive in order for recovery to work. Use instructions for Linux machine to re-mount the folder.

More information

When using WinPE media, if there is not enough RAM on the machine for storing TapeLocation cache, recovery may fail with the error "Not enough disk space at X:\ProgramData\Acronis\BackupAndRecovery\TapeLocation for storing cached data." At the moment there is no workaround for this.
