About recovery of dynamic/GPT disks and volumes with Acronis Small Office: Server Cloud Backup

Restoring disks and partitions in Windows and from Acronis Bootable Media

Table of Windows Editions and dynamic disk types they support

You need to have unallocated space on the disk with the partition the size of which you intend to increase


  1. Using Acronis Disk Director 11 in Windows XP, you create a new volume and set a label to it:

  2. After committing the operation, the Windows XP Explorer shows no label:

A newly created NTFS volume has "Full control" security permission for Everyone

This is a known limitation. As a workaround, copy all volumes from the flash drives to one folder. You will then be able to restore

Maximum partition/volume size supported by Acronis software


Now that I've migrated from SFM to Acronis Files Connect (formerly ExtremeZ-IP), my Mac clients fail to auto-mount volumes. What's wrong?



The first thing to check is to look in the "Acronis Files Connect Administrator" program and see if the "Allow Workstations To Save Password" button is checked. If this is not checked, then workstations will not be able to log in at start up correctly. Turn this option on, then remount the servers from the clients and set up the auto-mounting again.


I have been using the "mount volume" command to mount AppleTalk-based AFP server volumes. This command doesn't seem to work with Acronis Files Connect (formerly ExtremeZ-IP) servers. What's wrong?



The original "mount volume" scripting addition works only for AppleTalk volumes. This command used the following syntax:

mount volume "volume" on server "server" in AppleTalk zone "zone"

You can hide a volume from the operating system. After hiding, the operating system will not be able to detect the volume.

The hidden volume loses its letter and this letter becomes free for assignment.

(!) You can only hide and unhide volumes on basic MBR disks.

Hiding dynamic disks is not supported:

Conversion of both basic to dynamic and dynamic to basic is performed without data loss.

Conversion of a dynamic system disk to basic will require a reboot.

If the flash drive is formatted in FAT32, then the size of one file is limited to 4 GB


You receive an e-mail notification with backup log, containing one or multiple lines with "Volume Tracker has failed to find changes on volume..."
