
Acronis Secure Zone is always created at the end of the hard disk. When calculating the final
layout of the volumes, the program will first use unallocated space at the end.

If there is no or not enough unallocated space at the end of the disk, but there is unallocated
space between volumes, the volumes will be moved to add more unallocated space to the end.

When all unallocated space is collected but it is still not enough, the program will take free space
from the volumes you select, proportionally reducing the volumes' size. Resizing of locked
volumes requires a reboot.

However, there should be free space on a volume, so that the operating system and applications
can operate; for example, for creating temporary files. The program will not decrease a volume
where free space is or becomes less than 25% of the total volume size. Only when all volumes on
the disk have 25% or less free space, will the program continue decreasing the volumes
proportionally.
As is apparent from the above, setting the maximum possible zone size is not advisable. You will end
up with no free space on any volume which might cause the operating system or applications to work
unstably and even fail to start.
7.2.2 Managing Acronis Secure Zone
Acronis Secure Zone is considered as a personal vault (p. 210). Once created on a managed machine,
the zone is always present in the list of Personal vaults.
All the archive management operations available in vaults are also applicable for Acronis Secure Zone.
To learn more about archive management operations, see Operations with archives and backups (p.
147).
7.2.2.1 Increasing Acronis Secure Zone
To increase Acronis Secure Zone
1. On the Manage Acronis Secure Zone page, click Increase.
2. Select volumes from which free space will be used to increase the Acronis Secure Zone.
3. Specify the new size of the zone by:

dragging the slider and selecting any size between the current and maximum values. The
maximum size is equal to the disk’s unallocated space plus the total free space of all selected
partitions;

typing an exact value in the Acronis Secure Zone Size field.
When increasing the size of the zone, the program will act as follows:

first, it will use the unallocated space. Volumes will be moved, if necessary, but not resized.
Moving of locked volumes requires a reboot.

If there is not enough unallocated space, the program will take free space from the selected
volumes, proportionally reducing the volumes' size. Resizing of locked partitions requires a
reboot.
Reducing a system volume to the minimum size might prevent the machine's operating system from
booting.
4. Click OK.
