Microsoft Azure Blob Storage

If your backup storage destination is Microsoft Azure, and you have the General Purpose v2 Azure account, select the required Azure Blob Storage.

The following options are available:

• Hot tier. An online tier optimized for storing data that is accessed or modified frequently. The hot tier has the highest storage costs, but the lowest access costs.
• Cool tier. An online tier optimized for storing data that is infrequently accessed or modified. Data in the cool tier should be stored for a minimum of 30 days. The cool tier has lower storage costs and higher access costs compared to the hot tier.
• Cold tier.An online tier optimized for storing data that is rarely accessed or modified, but still requires fast retrieval. Data in the cold tier should be stored for a minimum of 90 days. The cold tier has lower storage costs and higher access costs compared to the cool tier.
• Archive tier. An offline tier optimized for storing data that is rarely accessed, and that has flexible latency requirements, on the order of hours. Data in the archive tier should be stored for a minimum of 180 days.

To learn more about the difference between Azure storage tiers, refer to the Azure Blob Storage - Hot, cool,cold, and archive storage tiers article at docs.microsoft.com.

Configure Application-Consistent Backups

You can configure the application processing settings on the Select Virtual Machines step of the Hyper-V backup wizard.

By default, the Try application processing setting is set. Click on the setting to change it, if necessary.

The following options are available:

• Try application processing. Back up virtual machines 'as is' if failed. Once this option is selected, virtual machines are backed up one by one. Using the installed VMware Tools, the state of applications running on virtual machines is checked, then a snapshot is made and an application-consistent backup is performed. In case an application-consistent snapshot is not made for some reason, a regular snapshot is done for this virtual machine.
• Require successful application processing. Skip virtual machines if failed. Once this option is selected, virtual machines with applications that did not flush pending I/O operations from memory to disks, are skipped and an appropriate warning is displayed for a user.
• Disable application processing. Back up virtual machines 'as is'. Once this option is selected, regular VM snapshots are done without quiescing.

Click Next.

Compression and Encryption Options

MSP360 (CloudBerry) Backup offers compression to reduce the storage space required for your backup and to speed up the upload process to the target storage.

Compression

MSP360 (CloudBerry) Backup offers compression to reduce the storage space required for your backup and to speed up the upload process to the target storage.

Encryption

You can protect your backup by encrypting its contents. MSP360 (CloudBerry) Backup supports AES encryption with key sizes of 128, 192, and 256 bits. A larger key size provides stronger encryption but may increase the time required for processing your backup. For more details on AES encryption, refer to the Advanced Encryption Standard.

If you choose to save your backup plan configuration to the destination storage, be aware that the encryption password is not stored in the configuration file for security reasons. Ensure that you save this password securely, as it will be required to restore the backup's contents.

Click Next to proceed.

Amazon S3-Specific Settings

If you are using Amazon S3 as your destination storage, the backup wizard provides additional options for encrypting data stored on Amazon cloud servers.

The following additional settings are available when using Amazon S3 for storing your backup:

• Use the Amazon key Management Service master key. Selecting this option allows Amazon S3 to decrypt data for users with permissions to access the object in the cloud and use the specified master key.

See What is AWS Key Management Service for more information.

Schedule

Specify the backup plan schedule settings.

The following options are available:

• Select the No schedule option to run the backup plan manually.
• Select the Simple (Forever Forward) option to apply the Forever Forward Incremental (FFI) schedule.
• Select the **Advanced (GFS, Object Lock) option to apply the recurring schedule and, if necessary, use Grandfather-Father-Son and Object Lock (Immutability).
• To set the time limit for plan execution, select the Stop the plan if it runs for checkbox, then specify the backup plan duration limit.
• To run the backup plan after the computer is on in case the backup plan run has been missed, select the Run missed scheduled backup immediately when computer starts up checkbox.

Click Next.

Simple Schedule

Select the Simple (Forever Forward) option to use the Forever Forward Incremental (FFI). This schedule offers one full backup followed by a limited number of incrementals. Once the limit is exceeded, a new full backup is created using in-cloud copying (synthetic full backup). Once you select this option, specify the FFI schedule for the backup plan. You can select the Daily or Monthly schedule type, depending on how often the incremental backups will be performed.

This schedule is unavailable if the selected storage account does not support synthetic full backups.

Advanced Schedule

Select the Advanced (GFS, Object Lock) option to set up a flexible, recurring schedule with generations. Every generation contains one full backup followed by incrementals.

The advanced schedule allows configuring a flexible schedule according to your requirements. To use this schedule you shoud add schedules for full and incremental backup runs:

• To create incremental backups by schedule, select the Recurring (Incremental) checkbox, then configure the schedule for incremental backups on a daily or monthly basis.
• To create full backups by schedule, select the Execute full backup (Synthetic full if possible) checkbox, then configure the schedule for full backups on a daily or monthly basis.

Retention Policy, GFS and Object Lock

Specify the retention policy settings for the backup plan. The retention policy depends on the schedule selected on the previous step.

Retention Policy with Simple Schedule

If you selected the Simple (Forever Forward Incremental) schedule, the Retention Policy step offers the following settings:

• Keep backup for. Select this option to limit the number of restore points. The Keep backup for value defines the period Restore Points with the Forever Forward Incremental schedule are kept. If their retention period expires, these restore points are merged into a full backup (with Forever Forward Incremental only one full backup is kept on the backup storage).

• Intelligent Retention: Each time the backup plan is executed, the backup storage parameters are analyzed automatically, setting the retention period based on storage provider data deletion conditions. This feature is enabled by default.

Retention Policy with Advanced Schedule / No Schedule

If you selected the Advanced (GFS, Object Lock) schedule or to run backup manually without the schedule, the Retention Policy step offers the following settings:

• Do not purge (Keep backup forever). Select this option to keep all your backup runs.
• Keep backup for. Select this option to limit the period while backup contents are kept in the backup storage, then specify the period.

To apply the GFS retention policy for the backup plan, select the Enable GFS checkbox, then customize the GFS retention policy by enabling the required keeping periods (weekly, monthly and yearly purge delays).

If backup data is required to be locked, enable the Object Lock (Immutability) checkbox.
