Standard Restore Procedure
SEP sesam restore is a process that browses for different versions of savesets and copies data from savesets to a client, thus recreating the original data. The restore wizard is triggered from the Menu bar -> Activities -> Restore.
Restore tasks can be saved, scheduled and run automatically in continuous intervals to check and control data integrity. For details, see SEPuler.
Data restore granularity depends on the selected data type.
The following restore types are available:
- Complete restore
- A process by which an entire saveset is restored - all the files of a saveset are selected and restored.
- Selective restore
- Only a subset of a saveset's files is selected - only selected parts of data on the saveset, such as individual files and directories, are restored.
- Generation restore
- All generations of backed-up files, including differential or incremental backup files, can be browsed for and selected for restore. SEP sesam automatically switches to the generation view in which all the generations of the files are presented. The selection list displays all files since the last full backup.
Configuring a restore task
A restore task involves browsing and selecting the desired savesets by time and task/filename, selecting restore type and restore target (the file system folder, for example) and other additional options. Restore can be run immediately or scheduled to run automatically at a specified time.
- Depending on what you want to restore, make sure that you have the proper restore permissions and access rights.
- Make sure that there is sufficient free space on the target system to which you are restoring your data.
- From the SEP sesam GUI menu bar, select Activities -> Restore. The New restore task window opens.
- Select the saveset you want to restore. You can search savesets by task name or by filename or path.
- If searching by task name, use the drop-down list of available tasks and select the one you want to restore from. This option is selected by default.
- If searching by filename/path, select the option Filename or path in saveset and enter your search expression in the search pattern field.
- Under the Saved in period drop-down lists, specify the time frame for which you want to conduct the search. Click Next.
- The search results are displayed. From the list of savesets matching your query, select the desired version by clicking on it, then select other relevant restore options (complete/generation restore). As of SEP sesam version 4.4.2, you can also select the option Mount saveset under Single File Restore to mount the target saveset to the disk and make it accessible as if it was a separate volume on the disk. You can mount any saveset stored to default data store Path or to Si3 data store. Mounting is not possible if the savesets are stored to tapes or if the data is compressed or encrypted. For advantages on mounting a saveset, see Cross-platform recovery file system layer (XPRFS). Click Next.
- If you selected the Mount saveset option (available only on SEP sesam version 4.4.2 or higher), a mount action is triggered. The selected saveset is mounted to the SEP sesam home directory var\tmp\mnt, e.g., C:\Program Files\SEPsesam\var\tmp\mnt\save_set_ID.
Click Next to display the Select files dialog. If you choose not to mount the saveset, this dialog is displayed immediately. Select the data you want to restore and click Next.
- Review your configured restore task and set additional options, if necessary.
- Details of the selected saveset are displayed at the top of the window. The name of the restore task is automatically generated in the Name field. You can edit the name and insert a comment below.
- The Drive field shows the drive with backed up data. Optionally, select the drive number of the drive that will be used to read the data. Typically, you use this if you have configured additional drives and you want to assign dedicated drives for the restores. For details, see the option Create second drive (introduced in SEP sesam 4.4.3 Tigon) in Configuring a Data Store.
- The Interface field shows the server (RDS server or Sesam server) with the attached data storage containing the selected saveset.
- The Target node drop-down list shows the target server to which the data will be restored.
- Under the Target Path, choose between the Restore to original target path or New restore target options. If you wish to choose a new restore target, enter its target path or browse for it.
- Under the Execution options drop-down list, select one of the following options:
- do not overwrite existing files (set by default): the data will not be restored if it already exists on the target server
- overwrite existing files: if data exists on the target server, it will be replaced by the restored version
- create a new version: if data exists on the target server, the restored data will be restored under a different name
- You can specify additional restore settings by clicking the Expert options button: modify the log level settings, define the pre/post script for restore, etc. For details, see the Restore Wizard.
- To start your restore immediately, click Start. To save the restore task, click Save.
- If you chose to mount a saveset (available only on SEP sesam version 4.4.2 or higher), click Next to unmount it and close your restore session.
|A restore task can be scheduled like any other task. If you want to add a restore task to the schedule, see Scheduling Restore.|
You can view the status of your restore jobs by selecting Job state -> Restore from the Main selection. Restore overview provides detailed information on the last run of restore jobs, including the task name, status (successful, error, in queue ...), start and stop time of the last backup, data size, throughput, client and message.
