- +      [[public:module:​microsoft_exchange_mail_level_2016:​on_remote_standalone|Standalone Scenario]] 
-  ​Flexible backup options +      [[public:module:microsoft_exchange_mail_level_2016:on_remote_dag|DAG Scenario]]
-    * Only select the required mailboxes, specific folders or items for backup. +
- +
-  * Flexible restore options +
-    * Restore the whole mailbox contents or just one email. +
-    * Restore mail items to the original mailbox or an alternate mailbox +
-    * Restore mail items to an alternate mailbox on another email domain +
- +
-==== Unlimited Versioning ====  +
-CloudBacko Pro provides backup and restore option for different version of exchange server to fulfill your requirement. +
- +
-==== Flexible Scheduling ====  +
-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.  +
- +
-  * 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 +
- +
-==== High Level of Security with AES 256-bit Encryption ====  +
-We understand your Exchange mail objects 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 default encrypt the backup data locally with AES 256-bit truly randomized encryption key. +
- +
-==== Better Performance ====  +
- +
-<WRAP indent>​ +
- +
-=== Multi-thread Backup === +
-The 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 MS Exchange 2016 mail level backup sets supports+
-  * Backup of 4 mailboxes concurrently (4 threads)  +
-  * For each of the 4 mailboxes, now supports a maximum 4 mail items concurrently (4 threads). \\ {{public:cloudbacko_module_exchange_2016_mail_106.png?​640}} \\ As shown the technology translate into a total of 16 concurrent threads compared with a total 4 concurrent backup threads for Exchange 2007/ 2010/ 2013 mail level backup. +
- +
-=== Improved Index File Structure === +
-The index file structure has been re-designed to improve the backup and restore performance. Each Exchange 2016 mailbox will have its own individual index file instead of a single index file for all mailboxes within the backup set. +
- +
-{{public:cloudbacko_module_exchange_2016_mail_107.png?​640}}  +
- +
-This new design eliminates any potential I/O performance bottlenecks when the index file is updated during each backup job, which can occur when using single index file structure for multi-thread concurrent backup. +
- +
-</​WRAP>​  +
- +
-==== High Reliability ====  +
-The implementation of one index file per mailbox can significantly improve the overall resilience of backup and restore from index related issues. +
- +
-{{public:cloudbacko_module_exchange_2016_mail_108.png?​640.png}} +
- +
-For example, if a single index file is corrupted, it will only affect the corresponding mailbox, while other mailboxes selected for backup are unaffected. +
- +
-==== Cloud Destination ​Backup ​==== +
-To offer you with the highest flexibility of backup destination,​ you can now back up mail objects 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. The list of supported destination can be found here: [[https://​www.cloudbacko.com/​en/​cloudbacko-advanced-cloud-local-server-workstation-amazon-S3-google-backup-software-features.jsp|supported cloud destinations]] +
- +
-==== Flexible Deployment Options ==== +
-CloudBacko Pro supports Mail Level backup and restore of Exchange Server 2016 by installing the client agent either on the Exchange server hosting the database, or on a remote backup machine.  +
- +
-Below is a comparison table on the differences on backup and restore with CloudBacko Pro  installation on an Exchange server and on a remote backup machine. +
- +
-^   ^ On Server Backup ^ Remote Backup ^ +
-^ Backup | Backup jobs will utilize the Exchange server’s resources, so it may impact the server performance. If the load on Exchange server is already high, this can impact the backup performance. \\ \\ * There is minimal performance issue with the transfer of mail items from the Exchange mail store to AhsayOBM. | * Backup jobs will utilize the remote backup machine’s resources, therefore, there is minimal impact on the Exchange server performance. ​ \\ \\ * Backup performance can be affected by the network connection speed between the Exchange server and the remote backup machine, especially for connection over the Internet. \\ \\ * General backup performance issues can be easily resolved by installing AhsayOBM on a more powerful backup machine. | +
-^ Large Number of MailboxesLarge Number of Mailboxes | * Backup of a large number of mailboxes can take more time to complete. \\ \\ For example, it may not be possible to run multiple mail level backup sets concurrently on the Exchange server for 1000 user mailboxes, as it may affect the server performance,​ so administrator may be limited to start one backup set at a time. \\ \\ 1 backup set can only have a total of 16 concurrent threads by default. | * Backup of a large number of mailboxes can take less time to complete. \\ \\ For example, 1000 user mailboxes can be divided into 5 separate backup sets of 200 mailboxes each. The 5 backup sets can be started concurrently on 1 machine or started by multiple machines. \\ \\ 5 backup sets * 16 concurrent threads = 80 concurrent threads | +
-^ Backup Scheduling | * For environment with limited backup window, there may not be sufficient time to complete both database and mail level backup jobs on a daily basis. | * For environment with limited backup window, remote backup may be a good option as the mail level backup can be completed remotely, while the database backup can be completed on the Exchange server at the same time period. \\ \\ * Continuous backup can be enabled without significant impact on the Exchange server performance,​ as backup jobs will utilize the resources of the remote backup machine. | +
-^ Restore | * The restore of mailbox items to another (standby) MS Exchange server, requires installation of AhsayOBM on the new MS Exchange server. | * Easily restore mailbox items to another (standby) MS Exchange server, without the need to reinstall AhsayOBM. \\ \\ * Restore mailbox items without direct / physical access to the MS Exchange server. \\ \\ * Restore performance can be affected by any network connection issue between the Exchange server and the remote backup machine, especially if the connection is over the Internet. | +

- +
-==== Microsoft Exchange Add-On Module ==== +
-One Microsoft Exchange Add-on Module is required for the backup of all user mailboxes. No license is required for public folder. +
- +
-==== Java Heap Size ====  +
-The default Java heap size setting on CloudBacko Pro is 2048MB. For Exchange 2016 mail level backup, it is highly recommended to increase the Java heap size setting to be at least 4096MB to improve backup and restore performance. The actual heap size is dependent on amount of free memory available on your Exchange 2016 server. +
- +
-==== Temporary Directory Folder ==== +
-Temporary Directory folder is used by CloudBacko Pro for storing backup set index files and any incremental or differential delta files generated during a backup job. To ensure optimal backup/​restoration performance,​ it is recommended that the temporary directory folder is located on a local drive with sufficient free disk space. +
- +
-==== Scheduled Backup for Exchange Server in Data Availability Group (DAG) ==== +
-Scheduled backup is required if you choose to back up in DAG option on Exchange server as CloudBacko Pro on all DAG members will base on the scheduled backup time to start backup on all the individual DAG member at the same time. +
-  * A DAG backup cycle is considered complete only when scheduled backup on all DAG members have been carried out. An email report will be generated when a complete DAG backup cycle has taken place.  +
-  * Please keep in mind that manual backup will only be considered as individual Mail Level backup, and therefore will not be counted as part of the DAG backup cycle. However, for backup and restore on a remote backup machine, as the operation for single node can be done either manually or automatically,​ a scheduled backup is not required. +
- +
-==== Mailbox Role ==== +
-Ensure all nodes have mailbox role. This can be checked by accessing the Exchange admin center (EAC).  +
- +
-{{public:cloudbacko_module_exchange_2016_mail_109.png?​640.png}}  +

- +
-===== Best Practice and Recommendation ===== +
-The following are some best practices or recommendations we strongly recommend you follow before you start any Exchange Server 2016 Mail Level backup and restore.  +
- +
-  * Mail Level Backup must be utilized in conjunction with Database Level Backup to fully protect an Exchange Server. +
-  * Active Directory server should be protected by regular full Window System Backup at least once every two weeks. +
-  * For CloudBacko Pro installed ​on Exchange Server, enable scheduled backup jobs when system activity is low to achieve the best possible performance. +
-  The remote backup machine should be on the same LAN as the MS Exchange server for optimal backup and restore performance. +
-  * To provide maximum data protection and flexible restore options, it is recommended to configure+
-    At least one offsite or cloud destination +
-    * At least one local destination for fast recovery +
-  * 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's 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. +
-  * **Distributed Backup Solution:** For backup of multiple or mass backup sets, to achieve better backup performance and to minimize any unnecessary loading on the Exchange server, please consider deploying CloudBacko Pro on remote backup machines as distributed backup solution instead of on the MS Exchange server. +
-  * For backup of a large number of mailboxes, it is recommended to divide all mailboxes into multiple backup sets. By default, the MS Exchange 2016 mail level backup ​module ​can back up a maximum of 4 mailboxes concurrently (4 concurrent backup threads), while backing up a maximum of 4 mail items concurrently per mailbox (4 concurrent backup threads). Therefore, each backup set supports a maximum of 4x4=16 backup threads at a time. By splitting up all mailboxes into separate backup sets, the more backup sets, the faster the backup process can achieve.  +
-<WRAP indent><​WRAP indent>​ +
-Example-1There are 100 mailboxes that need to be backup, you can divide 20 mailboxes into one backup set. +
- +
-^ Backup Set Name ^ Mailbox Number ^ +
-| Backup-Set-1 | No.1 -- 20 |  +
-| Backup-Set-2 | No.21 -- 40 |  +
-| Backup-Set-3 | No.41 -- 60 |  +
-| Backup-Set-4 | No.61 -- 80 |  +
-| Backup-Set-5 | No.81 -- 100 |  +
-<WRAP info> +
-If there are new mailboxes added, you can create new backup set for the new mailboxes. +
-</​WRAP>​ +
- +
-Example-2There are 100 mailboxes that needs to be backup, you can divide mailboxes into backup sets in alphabetic order. +
-^ Backup Set Name ^ Mailbox 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 mailboxes added, you can add the new mailboxes into the original backup set by the corresponding alphabetic order. +
