Veeam Backup Repositories

Veeam Plug-ins store backup files in repositories added to the Veeam Backup & Replication infrastructure. In this section, you can find the list of supported backup repositories and limitations for Veeam Plug-in backups.

Supported Backup Repositories

Veeam Plug-in for SAP HANA supports integration with the following types of repositories added to the Veeam Backup & Replication infrastructure:

• Windows Server
• Linux Server
• CIFS (SMB) Share
• Dell Data Domain Boost
• Quantum DXi
• ExaGrid

• HPE StoreOnce. If you plan to use HPE StoreOnce as a backup repository for Veeam Plug-in backups, the total number of stored files (data and metadata) must not exceed 3,000,000 per Catalyst store. If necessary, multiple Catalyst stores may be created on the same StoreOnce system.

• NFS File Share

You can also use scale-out backup repositories that contain repositories supported by Veeam Backup & Replication.

Backup Repositories Limitations

• For Veeam Plug-in backups, the warning which indicates that free space on a storage device has reached a specified threshold is configured in the veeam_config.xml file of Veeam Plug-in. The warning settings in the Veeam Backup & Replication console does not affect this setting.

To configure the warning settings, add the following parameter in the veeam_config.xml file.

• The plug-in configuration wizard will not show repositories where the Encrypt backups stored in this repository option is enabled. To learn how to disable the encryption option, see Access and Encryption Settings on Repositories.

If you want to use the same backup target with the repository-based encryption and Veeam Plug-ins, create a second repository in the subfolder for Veeam Plug-in backups.

• Veeam extract utility cannot extract Veeam Plug-in backup files.

Veeam Scale-Out Backup Repositories

If you want to store Veeam Plug-in backups on scale-out backup repositories, mind the following:

• If a scale-out repository is configured in the Data locality policy, each time BR*Tools starts a new channel for transferring backup files, Veeam Plug-in checks the free space in the extents and selects a scale-out backup repository extent that has the largest amount of free space. If there are two extents with one slot on each extent, the backup will be launched in two parallel streams (one on each extent).

• For Veeam Plug-in backups and backup copies, the Performance policy of a scale-out repository functions differently:

1. Veeam Backup & Replication checks if there are extents without warning on free space insufficiency. If all extents have the warning, Veeam Backup & Replication uses an extent with the largest amount of free space that has a free task slot.
2. If there are extents without the warning, Veeam Backup & Replication checks if there are incremental extents with free task slots. If there are no incremental extents with free task slots, Veeam Backup & Replication uses a full extent with the least amount of used task slots.
3. If there are incremental extents with free task slots, Veeam Backup & Replication will send backup files to an incremental extent with the least amount of used task slots. If the amount of used tasks is the same, an extent with the largest amount of free space.

To learn more about file placement policies of scale-out repositories, see Backup File Placement section of the Veeam Backup & Replication guide.

• If you want to add a backup repository as an extent to a scale-out backup repository and Veeam Plug-in backups are present on this backup repository, you must do the following:

1. In the Veeam Backup & Replication console, select Veeam Plug-in backup files that reside in this backup repository and remove them from configuration. For details, see Removing backups from configuration. Note that this action does not delete the backups from the repository.
2. In the Veeam Backup & Replication console, delete the Veeam Plug-in backup job. For details, see Deleting Jobs.
3. Add the repository as an extent to the scale-out repository. For details, see Extending Scale-Out Repositories.
4. Rescan the scale-out repository. For details, see Rescanning Scale-Out Repositories.

5. On the Veeam Plug-in server, set the scale-out repository as the target for backups using the following command:

6. Map the imported backups using the following command:

Capacity Tier

You can configure Veeam Backup & Replication to transfer Veeam Plug-in backup files to a capacity tier. Both policies (Move policy, Copy policy) are supported for Veeam Plug-in backups with the following limitations:

• For Veeam Plug-in backup files, capacity tier does not verify whether data that is being moved is unique and has not been offloaded earlier. Thus, it is highly recommended to check the pricing plans of your cloud storage provider to avoid additional costs for offloading and downloading backup data.

• Capacity tier does not track dependencies of full and incremental Veeam Plug-in backup files. Thus, mind the following:
• [For the Move policy] When backup files are transferred to the capacity tier, Veeam Backup & Replication takes into account only the creation time of backup files. Make sure that the operational restore window is not longer than the whole backup chain cycle period. Otherwise, you may encounter the scenario when full backup files are transferred to the capacity tier and their increment backup files still remain in the performance tier.
• The capacity tier immutability expiration date does not have the additional block generation period. The immutability expiration date is based only on the number of days specified in settings of the object storage backup repository.

• If a scale-out repository is down, you cannot restore from Veeam Plug-in backup files stored on a capacity tier. In this case, you can only import the backup files manually and then perform data recovery operations.
