-===== Requirements ===== +
- +
-==== Hardware Requirement ==== +
-To achieve the optimal performance when AhsayOBM is running on your machine, refer to this article for the list of hardware requirements:​ [[public:​8000_faq:​ahsay_hardware_requirement_list_hrl_for_version_8.1_or_above|Ahsay Hardware Requirement List (HRL)]]  +
- +
-==== Software Requirement ==== +
-Make sure the operating system where you have the Office 365 installed is compatible with the AhsayOBM. Refer to this article for the list of compatible operating systems and application versions: [[public:​8001_faq:​ahsay_software_compatibility_list_scl_for_version_8.1_or_above|Ahsay Software Compatibility List (SCL)]] +
- +
-==== Antivirus Exclusion Requirement ==== +
-To optimize performance of AhsayOBM on Windows, and to avoid conflict with your antivirus software, refer to the following ​Wiki article the list of processes and directory paths that should be added to all antivirus software white-list / exclusion list: [[public:​8014_faq:​suggestion_on_antivirus_exclusions|Suggestion on antivirus exclusions to improve performance of Ahsay software on Windows]] +
- +
-<WRAP info> +
-The bJW.exe process is automatically added to Windows Defender exclusion list for Windows 10 and 2016, and 2019 during installation / upgrade via installer or upgrade via AUA.  +
-</​WRAP>​ +
- +
-==== Other Requirements ==== +
- +
-<WRAP indent>​ +
-=== AhsayOBM Installation === +
-For agent-based backup and restore, make sure that the latest version of AhsayOBM is installed on your computer with Internet access for connection to your Office 365 account. +
-User should also stay up-to-date when newer version of AhsayOBM is released.  +
- +
-=== Office 365 Add-on Module Requirement === +
-Make sure that the Office 365 Backup feature has been enabled as an add-on module in your AhsayOBM user account and there is enough Office 365 Backup license quota to cover the backup of your users. +
- +
-Below is a sample screen shot of an AhsayOBM User with an add-on module of Office 365 with 20 licenses. +
- +
-{{public:​ahsay_wiki_module_office_365_03.png?​640}} +
-  +
-The licenses for the Office 365 module are calculated by the number of unique Office 365 accounts. If same Office 365 account is backed up on multiple backup sets with an OBM user account would be counted a one Office 365 license. +
- +
-If you are trying to backup SharePoint Sites under the Site Collections and/or files or folders under Public Folder, only one Office 365 license module is required. +
- +
-However, If you are trying to backup Items from Outlook, Items from OneDrive, Personal Sites under Users, the Office 365 license count will be calculated based on the number of the user account selected. +
- +
-=== Access for AhsayCBS User Web Console === +
-It is now possible to perform agentless backup and restore, which can be done via the AhsayCBS User Web Console without using the AhsayOBM client agent. In order to access the User Web Console, make sure you have Internet connection and a web browser installed on your computer or mobile device. +
- +
-=== AhsayOBM Licenses === +
-AhsayOBM licenses are calculated on a per device basis: +
- +
-== Agent-based == +
- +
-  - To backup users with one (1) backup client computer \\ Example: If one AhsayOBM is installed then, one AhsayOBM license is required. +
- +
-  - 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. +
- +
-== Agentless == +
- +
-  - To backup users using AhsayCBS User Web Console, one AhsayOBM license is required. +
- +
-== Backup Quota Requirement ==  +
-Make sure that your AhsayOBM user account has sufficient quota assigned to accommodate the storage of the Office 365 users for the new backup set and retention policy. ​  +
-Please contact your backup service provider for more details. +
- +
-== Continuous Backup Module == +
-The Continuous backup add-on module is required if would like to enable the continuous backup feature. +
- +
-== Java Heap Size == +
-The default Java heap size setting for AhsayOBM is 2048 MB / 2.048 GB. To avoid any inconveniences and ensure smooth operation when performing Office 365 backup, it is highly recommended to allot extra memory. +
- +
-Below is the table for the memory requirement:​ +
- +
-| Per OneDrive Account | 100 MB | +
-| Per SharePoint Site Collection | 150 MB | +
- +
-<WRAP info> +
-The memory requirement is dependent on the number of OneDrive or SharePoint Site Collections selected for backup. +
-The Java heap size to be configured should not exceed 2/3 of the RAM available, to allow sufficient resources for the operating system. +
-</​WRAP>​ +
- +

- +
-===== Best Practices and Recommendations ===== +
-The following are some best practices or recommendations we strongly recommend you 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. +
- +
-==== 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 AhsayOBM 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 running concurrently,​ the faster the backup process can be completed. +
- +
-==== Example Scenarios for Number of Users to Backup ==== +
- +
-<WRAP indent>​ +
-=== 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 |  +
- +
-<WRAP info> +
-If there are new users added, you can create new backup set for the new users. +
-</​WRAP>​ +
- +
-=== 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 | +
- +
-<WRAP info> +
-If there are new users added, you can divide the new users into the original backup sets by the corresponding alphabetic order. +
-</​WRAP>​ +
