1 Overview
What is this software?
Ahsay brings you specialized client backup software, namely AhsayOBM, to provide a set of tools to
protect your Office 365 user accounts. This includes backup and recovery of individual emails,
contacts, calendars and other mail items in your Office 365 Outlook, files on OneDrive and
SharePoint, with snapshots / versioning, and retention policy to protect even items that you may
have accidentally deleted from your Office 365 user account.
System Architecture
Below is the system architecture diagram illustrating the major elements involved in the backup
process among the Office 365 service, AhsayOBM and AhsayCBS.
In this user guide, we will focus on the software installation, as well as the end-to-end backup and
restore process using both AhsayCBS User Web Console (Agentless) and the AhsayOBM (Agent-
based).
1. Agentless: No need to install AhsayOBM. The AhsayCBS backup server connects to the
Office 365 directly through the Internet.
2. Agent-based: The latest version of AhsayOBM is installed on the remote backup machine
which is connected to Office 365 and AhsayCBS backup server through internet.
www.bobcloud.net 2
Why should I use AhsayOBM or AhsayCBS User Web Console?
We are committed to bringing you a comprehensive Office 365 backup solution with AhsayOBM.
Below are some key areas that we can help to make your backup experience a better one.
Easy Setup & Professional Services
Setup is a few clicks away - our enhanced AhsayOBM v8 can be easily downloaded and installed
in just a few clicks. The refined user interface also provides user-friendly instructions to guide you
through installation, configuration, backup and restore. The intuitive setup procedures together with
instructions in this user guide makes the software installation and operations easy even for layman
users. That being said, if you do run into any problems during setup, we are here to help out. Visit

www.bobcloud.net 3
Selectable Backup Run Type
You can choose to either run the backup set you created on Server (AhsayCBS User Web Console)
or Client (AhsayOBM).
Run on Server
A Run on Server Office 365 backup set provides you with an agentless backup solution. Manual or
scheduled backup job is performed on the backup server (i.e. AhsayCBS User Web Console); you
do not need to install a backup agent on your personal computer in order to back up your data on
cloud storages. The advantages of agentless backup technology make it a good option for users
who want to simplify the backup and restore management.
Run on Client
A Run on Client Office 365 backup set provides you with an agent-based backup solution. Manual
or scheduled backup job is performed on the client computer (i.e. AhsayOBM); you need to install a
backup agent on your personal computer in order to back up your data on cloud storages. The
advantages of agent-based backup technology make it a good option for users who want to have
more control on individual backup / restore and resources management.
Comparison between Run on Server and Run on Client
With both Run on Server (agentless) and Run on Client (agent-based) backup options available
and the freedom to use different setting on different backup sets according to your needs, our
backup solution offers you with high level of flexibility and efficiency for Office 365 backup and
restore.
Below is the comparison between backup and restore job Run on Server and Run on Client.
Run on Server
(AhsayCBS User Web Console)
Run on Client
(AhsayOBM)
Installation
No need to install the client backup
agent on your computer or upgrade
it when a newer version becomes
available, which can fulfill some
regulatory requirements of
compliance during backup or
Need to install the latest version
of AhsayOBM on computer with
internet access for connection to
Office 365 account.

restore.
Only a web browser and internet
connection is needed.
Backup
Backup operation of all users are
performed on the backup server,
which means multiple jobs may run
at the same time leading to slower
performance.
Backup period will be shorter as the
backup data are transferred directly
from Office 365 to AhsayCBS
backup server.
Backup destination is restricted to
AhsayCBS backup server.
Backup job is performed on your
computer with resources that is
dedicated to yourself.
In the event of a failure to a
single backup agent, it fails in
isolation to other users’
environment.
Backup period will be longer as
the backup data are transferred
from Office 365 to AhsayOBM,
then to AhsayCBS backup
server.
Backup destination can be
AhsayCBS backup server, local
and cloud drive and FTP.
Large
Number of
User
Backup
Sets
Backup of large number of user
backup set may take more time. As it
will increase the AhsayCBS server
load a lot if run multiple user backup
sets concurrently and may affect the
server performance, so it will make
backup speed slower and period
longer.
Backup of large number of user
backup sets may take less time.
As backup sets can be run
concurrently over several
machines as distributed solution,
the resource will be more and
will make backup speed faster
and period shorter.
Cost
Do not require provision of additional
Mac machine.
May require the provision of an
additional Mac machine.
Restore
Restore operation of all users are
performed on the backup server
which may have multiple jobs to run
at the same time, resulting in slower
performance.
Restore period should be shorter as
the backed up items are transferred
directly from AhsayCBS backup
server to Office 365.
Restore job is performed on your
computer with resources that is
dedicated to yourself.
In the event of a failure to a single
backup agent, it fails in isolation
to other users’ environment.
Restore period should be longer
as the backed up items are
transferred from AhsayCBS
backup server to AhsayOBM first
and then to Office 365.

Fast and Efficient
We understand that backup could be a time and resources consuming process, which is why
AhsayOBM is designed with advanced technologies to make backup a fast and efficient process.
We also understand that you may wish to run backup at a specified time interval of your choice,
that’s why we also allow you to set your own backup schedules so that you can take full control of
the time when to perform backup.
Multi-threading – this technology utilizes the computing power of multiple CPU cores for
creating multiple backup and restore threads to produce fast backup and restore performance.
The default setting for Office 365 backup sets supports
Backup of 4 users concurrently (4 threads).
For each of the 4 users, now supports a maximum 4 items concurrently (4 threads).
www.bobcloud.net 6
For Agentless Option:
For Agent-based Option:
As shown the technology translate into a total of 16 concurrent threads.
Index File Structure – The index file structure has been re-designed to improve the backup
and restore performance.
Each Office 365 user will have its own individual index file instead of a single index file for all
users within the backup set.
This new design eliminates any potential I/O performance bottlenecks when the index files
are updated during each backup job, which can occur when using single index file structure
for multi-thread concurrent backup.
Block Level Incremental Backup – this technology breaks down the backup files into
multiple blocks and only the changed blocks will be backed up each time.
Backup of Selected Items
www.bobcloud.net 7
To back up the Office 365 user accounts, the backup resources can be user level, site collection
level and even item level.
Flexible backup options:
Only select the required users, specific site collection or items for backup.
Flexible restore options:
Restore all the users or just one user, or restore the whole site collection or just one
site, or restore the whole user contents or just one item.
Restore items to the original location or an alternate location
High Level of Security
We understand your Office 365 users may contain sensitive information that requires to be
protected, that is why your backup data will be encrypted with the highest level of security measure.
Un-hackable Encryption Key – to provide the best protection to your backup data, you can
turn on the encryption feature which will be default encrypt the backup data locally with AES
256-bit truly randomized encryption key.
Encryption Key Recovery – Furthermore, we have a backup plan for you to recover your
encryption key in case you have lost it. You backup service provider can make it mandatory
for you to upload the encryption key to the centralized management console, the encryption
key will be uploaded in hashed format and will only be used when you request for a recovery.
Centralized Management Console
Our enriched features on the centralized web console offers you a one-stop location for monitoring
and managing your backup and restore. Below is an overview of what you can do with it. For more
details regarding the setup and operations of the centralized management console, refer to the
AhsayCBS v8 Administrator’s Guide for details.
Create/ update/ delete backup set

Cloud Destinations Backup
To offer you with the highest flexibility of backup destination, you can now back up Office 365 user
to a wide range of cloud storage destinations. Utilizing cloud destination backup gives you an extra
layer of protection in the event of a local drive corruption, where you will still be able to retrieve data
from the cloud destination.

Higher Reliability
The implementation of one index file per user can significantly improve the overall resilience of
backup and restore from index related issues.
For example, if a single index file corrupted, it will only affect corresponding user, while other users
selected for backup are unaffected.

browser installed on your computer or mobile device.
AhsayOBM Licenses
AhsayOBM licenses are calculated on a per device basis:
For Agent-based:
i. To backup users with one (1) backup client computer
Example: If one AhsayOBM is installed then, one AhsayOBM license is required.
ii. To backup users with multiple backup client computers, the number of
AhsayOBM licenses required is equal to the number of devices.
Example: If there are ten (10) users to be backed-up with three (3) backup client
computers, then 3 AhsayOBM licenses are required.
For Agentless:
i. To backup users using AhsayCBS User Web Console, one AhsayOBM license is
required.
Please contact your backup service provider for more details.
Backup Quota Requirement
Make sure that your AhsayOBM user account has sufficient quota assigned to

Best Practices and Recommendations
The following are some best practices or recommendations we strongly recommend you to follow
before you start any Office 365 backup and restore.
Temporary Directory Folder Location (For backup and restore running on
AhsayOBM only)
Temporary directory folder is used by AhsayOBM for storing backup set index files and
any incremental or differential backup files generated during a backup job. To ensure
optimal backup/restoration performance, it is recommended that the temporary
directory folder is set to a local drive with sufficient free disk space.
Performance Recommendations
Consider the following best practices for optimized performance of the backup
operations:
Enable schedule backup jobs when system activity is low to achieve the best
possible performance.
Perform test restores periodically to ensure your backup is set up and performed
properly. Performing recovery test can also help identify potential issues or gaps
in your recovery plan. It is important that you do not try to make the test easier, as
the objective of a successful test is not to demonstrate that everything is flawless.
There might be flaws identified in the plan throughout the test and it is important
to identify those flaws.
Set Backup Destination
After creating the backup set in Run on Client mode on AhsayCBS user web console,
please remember to login AhsayOBM to set the backup destination if you want the
backup destination to be Local/ Mapped Drive/ Removable Drive.
Backup Destination
To provide maximum data protection and flexible restore options for agent-based
backup, it is recommended to configure:
At least one offsite or cloud destination
At least one local destination for fast recovery
However, for Agentless Cloud storage there may be an impact on the backup
performance.
www.bobcloud.net 26
Login AhsayOBM
After modifying the backup schedule setting or Continuous Backup setting of the Run
on Client backup set on AhsayCBS user web console, please remember to login to the
AhsaOBM client once to synchronize the changes immediately.
Large amount of Users to Backup
It is recommended to divide the users into multiple backup sets. By default, the Office
365 backup module can back up a maximum of 4 users concurrently (4 concurrent
backup threads), while backing up a maximum of 4 items concurrently per user (4
concurrent backup threads). Therefore, each backup set supports a maximum of
4x4=16 backup threads at a time. By splitting up all users into separate backup sets,
the more backup sets, the faster the backup process can achieve.
For more detailed examples about the number of users to backup, refer to Appendix D:
Example Scenarios for Number of Users to Backup.

Scenario No. 4: Backing up Office 365 User Accounts, files and/or folders under Public
Folder, and SharePoint sites under Site Collections in multiple backup sets.
The required Office 365 license will depend on the number of unique Office 365 accounts.
Example No. 1: To back up one (1) Office 365 user account, files and/or folders under Public
Folder, and SharePoint sites under Site Collections on multiple backup sets, three (3) Office
365 licenses are needed.
Backup Set Name
Office 365 User Account, SharePoint
Site, and Files and/or Folders
Backup Set A
user01@company-office365.com
user01@company-office365.com
user02@company-office365.com
companyoffice365.sharepoint.com/user01
Backup Set B
companyoffice365.sharepoint.com/user02
user01@company-office365.com
user02@company-office365.com

Appendix C: Example Setting for Java Heap Size
These are some examples for better appreciation with formula for calculating the required memory:
Example No. 1: Backup set with 20 SharePoint Sites and 50 OneDrive Accounts
SharePoint Sites – 20 x 150MB = 3000 MB / 3 GB
OneDrive Accounts – 50 x 100MB = 5000 MB / 5 GB
Total = 3000 MB / 3 GB + 5000 MB / 5 GB = 8000 MB / 8 GB
In this example, we first computed for the memory needed for the SharePoint Sites and
OneDrive Accounts which are 3000 MB / 3 GB and 5000 MB / 5 GB respectively. Then we
added those two and came up with 8000 MB / 8 GB. This is the total Java heap size setting of
the AhsayOBM client should set.
Example No 2: Backup set with 80 Site Collections and 100 OneDrive Accounts
Site Collections – 80 x 150MB = 12000 MB / 12 GB
OneDrive Accounts – 100 x 100MB = 10000 MB / 10 GB
Total = 12000 MB / 12 GB + 10000 MB / 10 GB = 22000 MB / 22 GB
In this example, we first computed for the memory needed for the Site Collections and
OneDrive Accounts which are 12000 MB / 12 GB and 10000 MB / 10 GB respectively. Then
we added those two and came up with 22000 MB / 22 GB. This is the total Java heap size
setting of the AhsayOBM client should set.

Appendix D: Example Scenarios for Number of Users to Backup
Example No. 1: There are 1000 users needed to be backup, you can divide 200 users into
one backup set.
Backup Set Name
User Number
Backup -Set-1
No.1 -- 200
Backup -Set-2
No.201 – 400
Backup -Set-3
No.401 -- 600
Backup -Set-4
No.601 – 800
Backup -Set-5
No.801 – 1000
Note: If there are new users added, you can create new backup set for the new users.
Example No. 2: There are 1000 users needed to be backup, you can divide users into
backup sets in alphabetic order.
Backup Set Name
User Name Start with
Backup -Set-1
A -- E
Backup -Set-2
F -- J
Backup -Set-3
K --O
Backup -Set-4
P -- T
Backup -Set-5
U -- Z
Note: If there are new users added, you can divide the new users into the original backup
sets by the corresponding alphabetic order.
