Tape Backup Wizard: Options

On the Options page of the wizard, you can name the job and enable/disable network acceleration and encryption. In addition, you can set up pre and post actions and enable bandwidth throttling. 

Job Options

In this section, you can give a name to the tape backup job and enable/disable app-aware mode, change tracking, network acceleration, and encryption.

Job Name

Specify a name for the tape backup job in the Job name box.

Job Priority

Select a job priority level between 1 and 5, with 1 being the highest priority. Jobs with higher priority levels are prioritized by Transporters during job processing.

Notes

  • This option is only available in the Enterprise, Enterprise Essentials, Enterprise Plus, MSP Enterprise, and MSP Enterprise Plus editions.

  • If a tape backup job contains multiple backup objects, setting its Job Priority to 1 does not necessarily mean that the job finishes before lower priority jobs. This is because backup objects in Tape backup jobs are processed one by one, meaning that a Transporter is released after processing a given backup object. After the target tape cartridge for a subsequent backup object is found, a Transporter is assigned to the backup object with the highest priority.

Network Acceleration

Once Network Acceleration is enabled, NAKIVO Backup & Replication uses compression and traffic reduction techniques to speed up data transfer. Select this option if you are backing up over WAN without a VPN connection. For more information, refer to Network Acceleration. If the source backup is already compressed, it is recommended to enable Network Acceleration and make sure that the source Backup Repository and target tape device have the same compression level. For more information, see this article.

Note

The Network acceleration option is not available if the Backup encryption option is enabled.

Network Encryption

If the Network Encryption option is selected, backup data is protected with AES 256 encryption while traveling over the network. Data encryption increases the backup time and CPU load on machines running Transporters. Select this option if you back up over WAN without a VPN connection. For more information, refer to Encryption in Flight and at Rest.

Note
You need at least one Transporter at the source and target sites to enable network encryption.

Backup Encryption

When enabled, backup data is protected with AES 256 block cipher encryption with a 256-bit key length. You can protect the backup file by creating a new password or selecting an existing one.

For more information, refer to Enabling Backup Encryption.

Notes

  • This option is available only if the Disk or Tape destination type was chosen on the Destination page of the wizard.

  • The Backup encryption option is not available if the Network acceleration option is enabled.

  • If enabled, the created recovery points are encrypted.

  • The Backup encryption option is not displayed for a backup job where forever incremental repositories are selected as the only target repositories.

  • The Backup encryption option cannot be enabled if multiple targets with a mix of supported and unsupported (SaaS repositories or forever incremental repositories) repositories are selected as destinations.

  • It’s recommended that you enable the (AWS) Key Management Service. If KMS is enabled, all backup encryption passwords encrypted with the Key Management Service cryptographic key are available for recovery in case of product re-installation. For more information, refer to Enabling KMS.

Tape Backup Settings

In this section, select when you want the system to create full backups and set up the rules for data appending.

Creating Full Backup

With the Create full backup list, you can specify how often the system should perform a full (not incremental) backup to tape. The following options are available:

  • Always: Every backup will be full

  • Every: Select a day of the week. The full backup will be performed once a week on a specified day

  • Every 2nd: Select a day of the week. The full backup will be performed once in 2 weeks on a specified day

  • First: Select a day of the week. The full backup will be performed once per month starting with the first specified day of the month

  • Second: Select a day of the week. The full backup will be performed once per month starting with the second specified day of the month

  • Third: Select a day of the week. The full backup will be performed once per month starting with the third specified day of the month

  • Fourth: Select a day of the week. The full backup will be performed once per month starting with the fourth specified day of the month

  • Last: Select a day of the week. The full backup will be performed once per month starting with the last specified day of the month

  • Day #: Select the day number. The full backup will be performed once per month on the specified day number

  • Job runs #: Specify the number of backup jobs to pass before running a full backup

With the If a full backup fails, create a full backup on the next job run option selected, the next job run creates a full backup if the current job run fails to do so.

Note
Only Always and Job runs # options are always available for selection. The rest of the options' availability depends on the scheduling settings specified on the Schedule page.

Tape Appending

The Tape appending feature allows you to set up the rules for data appending. The following options are available:

  • Append previous tape if possible: 

    • The job run appends data to the last tape cartridge.

    • If the tape cartridge that was last written during the last job run is not available in the device or is full, the job starts with an empty cartridge:

      • All job objects within the job run are written to the selected tape cartridge one by one.

      • If the selected tape cartridge runs out of space, the next empty tape cartridge is selected and the process repeats until all job objects are written.

  • Start full backup with an empty tape: 

    • In case the backup modes of all job objects within the job run are defined as full:

      • The job run starts with an empty tape cartridge.

      • All job objects within the job run are written to the selected tape cartridge one by one.

      • If the selected tape cartridge runs out of space, the next empty tape cartridge is selected and the process repeats until all job objects are written.

    • In case the backup modes of all job objects within the job run are defined as incremental:

      • The job run appends data to the last tape cartridge.

      • All job objects within the job run are written to the selected tape cartridge one by one.

      • If the selected tape cartridge runs out of space, the next empty tape cartridge is selected and the process repeats until all job objects are written.

    • In case the backup modes of all job objects within the job run are defined as a mix of full and incremental modes:

      • The job run appends data to the last tape cartridge.

      • All job objects within the job run are written to the selected tape cartridge one by one.

      • If the selected tape cartridge runs out of space, the next empty tape cartridge is selected and the process repeats until all job objects are written.

  • Always start with an empty tape: 

    • The job starts with an empty tape cartridge.

    • All job objects within the job run are written to the selected tape cartridge one by one.

    • In case the selected tape cartridge runs out of space, the next empty tape cartridge is selected and the process repeats until all job objects are written.

Pre and Post Job Actions

NAKIVO Backup & Replication provides you with the ability to enable certain actions before a tape backup job begins and after it has completed. You can choose to send job run reports to the email provided and run local pre and post job scripts.
