- Tape backup of FlexVol volumes
ONTAP supports tape backup and restore through Network Data Management Protocol (NDMP). NDMP allows you to back up data in storage systems directly to tape, resulting in efficient use of network bandwidth. ONTAP supports both dump and SMTape engines for tape backup. - Managing tape drives
You can verify tape library connections and view tape drive information before performing a tape backup or restore operation. You can use a nonqualified tape drive by emulating this to a qualified tape drive. You can also assign and remove tape aliases in addition to viewing existing aliases. - Understanding tape drives
You must use a qualified tape drive that has been tested and found to work properly on a storage system. You can follow tape aliasing and also enable tape reservations to ensure that only one storage system accesses a tape drive at any particular time. - Transferring data using ndmpcopy
The ndmpcopy command transfers data between storage systems that support NDMP v4. You can perform both full and incremental data transfers. You can transfer full or partial volumes, qtrees, directories, or individual files. - Understanding NDMP for FlexVol volumes
The Network Data Management Protocol (NDMP) is a standardized protocol for controlling backup, recovery, and other types of data transfer between primary and secondary storage devices, such as storage systems and tape libraries. - Understanding NDMP for FlexGroup volumes
Starting with ONTAP 9.7, NDMP is supported on FlexGroup volumes. - Managing node-scoped NDMP mode for FlexVol volumes
You can manage NDMP at the node level by using NDMP options and commands. You can modify the NDMP options by using the options command. You must use NDMP-specific credentials to access a storage system to perform tape backup and restore operations. - Managing SVM-scoped NDMP mode for FlexVol volumes
You can manage NDMP on a per SVM basis by using the NDMP options and commands. You can modify the NDMP options by using the vserver services ndmp modify command. In the SVM-scoped NDMP mode, user authentication is integrated with the role-based access control mechanism. - Understanding dump engine for FlexVol volumes
Dump is a Snapshot copy based backup and recovery solution from ONTAP that helps you to back up files and directories from a Snapshot copy to a tape device and restore the backed up data to a storage system. - Understanding SMTape engine for FlexVol volumes
SMTape is a disaster recovery solution from ONTAP that backs up blocks of data to tape. You can use SMTape to perform volume backups to tapes. However, you cannot perform a backup at the qtree or subtree level. SMTape supports baseline, differential, and incremental backups. SMTape does not require a license. - Monitoring tape backup and restore operations for FlexVol volumes
You can view the event log files to monitor the tape backup and restore operations. ONTAP automatically logs significant backup and restore events and the time at which they occur in a log file named backup in the controller's /etc/log/ directory. By default, event logging is set to on. - Error messages for tape backup and restore of FlexVol volumes
You might encounter an error message when performing a dump backup or restore operation due to various reasons. - Contacting Support
You can contact Support to obtain help for your issue. - Notices
