3 OpenDirect Restore
What is OpenDirect Restore?
OpenDirect restore is an additional restore options for restoring files from a Windows File backup set
available from AhsayACB v7.13.0.0 or above. The OpenDirect restore method makes use of the
granular restore technology to make selective restore of individual files from a large compressed file
or image, for example zip, RAR, ISO files, without the need to restore the compressed file or image
first, to give you a fast and convenient file restore solution.
During the OpenDirect restore process, the file(s)/folders can be viewed and/or copied from the
Windows File Explorer on the Windows machine you are performing the restore. OpenDirect restore
is only supported on File backup sets created and backed up using AhsayACB v7.13.0.0 or above
on Windows platform with OpenDirect restore feature enabled.
IMPORTANT
OpenDirect restore requires an additional OpenDirect / Granular restore add-on module license to
work. Contact your backup service provider for further details.
www.bobcloud.net 4
How does OpenDirect Restore work?
www.bobcloud.net 5
Benefits of using OpenDirect Restore
Comparison between OpenDirect File Restore and Traditional File Restore
OpenDirect Restore
Introduction
OpenDirect restore allows you to quickly access individual files from a large compressed file or
image by viewing and/or copying files from the file explorer on the Windows machine you are
performing the restore, without having to fully restore the whole compressed file or image first.
Pros
Restore of Entire
Compressed File
Not Required
As opposed to the traditional restore where you have to restore the entire
compressed file or image first before you can access any individual file in it,
OpenDirect restore allows you to view and download individual files from a
compressed file or image, without having to restore compressed file or
image first.
Ability to Restore
Selected Files
When restoring a large compressed file or image, sometimes, you may only
need to restore individual file(s) out of the entire file, therefore, OpenDirect
restore gives you the flexibility to restore selective file(s) quickly, so it saves
you time and effort to achieve your restore goal.
Cons
No Encryption
and
Compression
To ensure optimal restore performance, the backup of the files in an
OpenDirect file backup set will NOT be encrypted and compressed,
therefore, you may have to take these factors in consideration when
selecting this restore option.
Traditional Restore
Introduction
The traditional restore method restores the entire compressed file or image. Backed up data can
only be accessed when complete restore is performed.
Pros
Backup with
Compression and
Encryption
Backup file(s) are compressed, therefore in smaller file size, and
encrypted before being uploaded to the backup destination.
Cons
Slower Recovery
As the entire compressed file or image has to be restored before you can
access any individual files, restore time could be long if the file size is
large
www.bobcloud.net 6
Requirements
Supported Backup Modules
OpenDirect restore is only supported on File backup sets created and backed up using AhsayACB
v7.13.0.0 or above on Windows platform with OpenDirect restore feature enabled.
License Requirements
An OpenDirect / Granular restore add-on module license is required per backup set for this feature
to work. Contact your backup service provider for more details.
Backup Quota Storage
As compression is not enabled for OpenDirect file backup sets, to optimize restore performance
the storage quota required will be higher than non-OpenDirect file backup sets. Contact your
backup service provider for details.
Windows Operating System
AhsayACB must be installed on a 32 bit or 64 bit Windows Operating System as libraries for
OpenDirect only supports Windows platform.
Windows 7 SP1 or above
Windows 8
Windows 8.1
Windows 10
Temporary Directory Requirement
The temporary directory folder should have at least the same available size as the compressed file
or image to be restored and should be located on a local drive to ensure optimal performance.
Available Spare Drive Letter
One spare drive letter must be available on the Windows machine for the OpenDirect restore
process, as the compressed file or image is mounted on Windows as a logical drive. AhsayACB
will automatically take the next available drive letter in alphabetical order for the mounted
compressed file or image.
Note
1. The Windows drive letters A, B, and C are not used by OpenDirect restore.
2. The OpenDirect restore assigned drive letter(s) will be released once you exit from AhsayACB UI.
Network Requirements
Recommended minimum network speed is at least 100Mbps download speed.
The network bandwidth requirements will increase in proportion to the size of the compressed
file/image and or the incremental delta chain length to ensure optimal performance. Working with
limited network bandwidth may severely affect the granular restore performance.
You can use an online network speed test website (e.g. www.speedtest.net) to get an idea of the
actual bandwidth of the machine.
www.bobcloud.net 7
Other Dependencies
The following dependencies are restore related and therefore they will be checked by AhsayACB
only when an OpenDirect restore is performed. Absence of these elements will not affect the
backup job but would cause the restore to fail.
Microsoft Visual C++ 2015 Redistributable (x86) / (x64)

on shared files or folders using a shared computer, it is recommended that you
enable Restore file permissions by ticking the checkbox so that the files restored
will not be fully accessible to everyone using the shared computer.
Delete extra files
By enabling this option, the restore process will attempt to synchronize the
selected restore source with the restore destination, making sure the data in the
restore destination is exactly the same as the restore source. Any data created
after backup will be treated as “extra files” and will be deleted from the restore
source if this feature is enabled.
Example:
i) Two files are created under the Document folder 01, namely doc 1 & doc 2.
ii) A backup is performed for folder Document folder 01.
iii) Two new files are created, namely doc 3 & doc 4.
iv) A restore is performed for the Document folder 01, with Delete extra files
option enabled.
v) Since doc 3 & doc 4 have never been backed up, therefore they will be
deleted from Document folder 01, leaving only the two files that have been
backed up.
WARNING
Please exercise extra caution when enabling this feature. Consider what data in
the restore destination has not been backed up and what impact it would cause if
those data is deleted.
Prior to the data restore and synchronization, a warning message shows as the
one shown below. Only clicking Yes will the “extra file” be deleted. You can click
Apply to all to confirm deleting all the “extra files” at a time.
