Checkpoint restart support

The following table addresses the use of checkpoint restart with different products and options.

Windows clients

The following items pertain to the use of checkpoint restart with Windows clients:

  • Checkpoint restart is not supported for backup selections indicated by a UNC path.

  • No checkpoints are taken during a System State backup.

  • No checkpoints are taken during a Windows Disk Image (raw) backup.

  • No checkpoints are taken for the remainder of the backup after NetBackup encounters Single-instance Store (SIS).

  • When an incremental backup resumes and completes successfully, the archive bits are cleared for the files that were backed up after the job resumed. However, the archive bits are not cleared for the files that were backed up before the resume. Since the archive bits remain, the files that were backed up before the resume are backed up again during the next incremental backup.

Multiple copies

Checkpoint restart is supported for the policies that are configured to create multiple backup copies.

See Multiple copies schedule attribute.

The last failed copy that contains a checkpoint can be resumed if all of the following items are true:

  • A copy is configured to allow other copies to continue the job if the copy fails and subsequent checkpoints occur.

  • The Take checkpoints every option is selected for this policy.

Synthetic backups

Checkpoint restart is not supported for use with synthetic backups in the current NetBackup release.

Snapshot Client

Checkpoint restart is supported for use with local or alternate client backups. However, the following methods are not supported: Block Level Incremental Backups, Media Server Copy, Third-Party Copy Device, and Instant Recovery backups.

Basic disk staging

Checkpoint restart is supported for use in Stage I of basic disk staging, during which data is backed up to disk.

Checkpoint restart is unavailable in the Stage II storage unit policy of basic disk staging, during which data is relocated to another storage unit.

NearStore storage units

NearStore storage units do not support checkpoint restart.

NetWare clients

Although NetWare clients can use the Standard policy type, checkpoint restart for backups is not supported on NetWare clients.
