![]() However, the archive bits are not cleared for the files that were backed up before the resume. When an incremental backup is resumed and completes successfully, the archive bits are cleared for the files that were backed up after the job resumed. Single-instance Store (SIS): No checkpoints are taken for the remainder of the backup after NetBackup encounters single-instance store. Windows Disk-Image (raw) backups: No checkpoints are taken during a Windows disk-image backup. ![]() System State backups: No checkpoints are taken during the backup of a System State. For more information, see “Staging backups to initial storage, then final storage” on page 238. Checkpoint restart is unavailable in the Stage II storage unit policy of basic disk staging, during which data is relocated to another storage unit. However, other methods are not supported: Block Level Incremental Backups, Media Server Copy, Third-Party Copy Device, and Instant Recovery backups.ĭisk staging storage units (used in basic disk staging): Checkpoint restart is supported for use in Stage I of basic disk staging, during which data is backed up to disk. Snapshot Client: Checkpoint restart is supported for use with local or alternate client backups. ![]() (See “VSP (Volume Snapshot Provider) properties” on page 486.) Veritas Volume Snapshot Provider (VSP): Checkpoint restart is supported for use with VSP. Take checkpoints every is selected for this policy. (See “Multiple copies” on page 137.) The last failed copy that contains a checkpoint can be resumed if the following items are true:Ī copy is configured to allow other copies to continue the job if the copy fails and subsequent checkpoints occur, and ![]() ■ Multiple Copies: Checkpoint restart is supported for the policies that are configured to create multiple backup copies. If the frequency of checkpoints impacts performance, increase the time between checkpoints. Balance more frequent checkpoints with the likelihood of time that is lost when a backup is resumed. (Default: 15 minutes.) The administrator determines checkpoint frequency on a policy-by-policy basis. The checkpoint frequency indicates how often NetBackup takes a checkpoint during a backup. Note: Although NetWare clients can use the Standard policy type, checkpoint restart for backups is not supported on NetWare clients. To see if this feature is supported for a specific agent or option, refer to the manual for that agent or option. Policy types MS-Windows-NT (for Windows clients) and Standard (for UNIX clients) support this policy attribute. (See “Schedule backup attempts” on page 431.) The Schedule backup attempts Global Attributes host property indicates the number of times that NetBackup tries a failed backup. Checkpoints are saved at file boundaries, and point to the next file in the list. Note that checkpoints cannot occur while a file is backed up. By taking checkpoints periodically during the backup, NetBackup can retry a failed backup from the beginning of the last checkpoint rather than restart the entire job. Without Take checkpoints every enabled, a failed backup restarts from the beginning of the job. Indicate how often the policy should take checkpoints.Ĭheckpoints during a backup are beneficial if a backup fails. The Take checkpoints every check box specifies whether NetBackup takes checkpoints during a backup job. Here under quotation from Admin guide vol 1 for windows: So once You do this You will be able to suspend this job and resume later on, In the policy properties for that client select the Take checkpoints every option.
