There are two ways to restore your data in SEP sesam: using the GUI restore wizard (described below), or via the web interface Restore Assistant. Even though most of the options are the same in both restore interfaces, the web Restore Assistant interface is designed to be more intuitive and offers additional advanced options while, on the other hand, it does not support the restore of all tasks types, such as PostgreSQL or Oracle. For details, see Restore Assistant.
SEP sesam GUI 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.
The data restore granularity depends on the selected data type. SEP sesam provides three basic restore types: complete, generation and selective restore. The restore type is specified when configuring a restore task in the Activities -> Restore.
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
Note that the following instructions for creating a restore task apply to using a restore wizard in the GUI. Although the steps and options are very similar, an alternative way for creating a restore task using the web interface is described in Restore Assistant and in Web Single File Restore for Virtual Machines.
A restore task involves browsing and selecting the desired savesets by time and task/filename, selecting the restore type and restore target (the file system folder, for example) and other additional options. The 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 restore permissions and access rights.
- Make sure that there is enough free space on the target system where you want to restore 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 a 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 that match your query, select the desired version by clicking on it, then select other relevant restore options (complete, generation, as path or disaster restore). 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 were a separate volume on the disk. You can mount any saveset stored to default data store Path, Si3 deduplication store or HPE StoreOnce. Mounting is not possible if the savesets are stored on 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.
- The Mount saveset option is available only in advanced UI mode (formerly expert GUI mode). To use the mount option, make sure your UI mode is set to advanced, as described in Selecting UI mode.
- To be able to access and mount the VM disk image on Linux, the guestfs-tools package must be installed on your SEP sesam Server or Linux RDS. If the guestfs-tools package is not installed on your SEP sesam Server or Linux RDS, it is not possible to mount VMDK and perform SFR. Refer to Installing guestfs-tools on Linux.
- As of v. 5.0.0 Jaglion, the Hide migrated option is no longer available. The migrated savesets are only displayed if there is no original (backup) saveset. If you want to use the migrated saveset instead of the original saveset for restore, you need to select it as Preferred Media pool in the Target Settings window (see step 6 below).
- If you have selected the Mount saveset option, 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 required. The details of the selected saveset are displayed in the upper part of the window. The options diffes slightly when restoring a virtual machine.
- The name of the restore task is automatically generated in the Name field. You can edit the name and add a comment below.
- The Target node drop-down list shows the target server to which the data will be restored.
- Under the Target path settings, select between the following options:
- Restore to original target path or Restore to original VM (in the case of a VM restore): The data will be restored to the same location from which it was backed up.
- New restore target or Change VM target selection (in the case of a VM restore): The data will be restored to another location. Use the Browser button to select the target directory for the restore or enter the path to the target directory manually.
- Restore with new VM name: Relevant only for VM restore; the VM will be restored to the original or a different location with a new VM name.
- Under the Execution options or VM restore options (in the case of a VM restore) drop-down list, select one of the following options:
- Do not overwrite existing items (set by default): The data will not be restored if it already exists on the target server.
- Overwrite existing items: If data exists on the target server, it will be replaced with the restored version.
- Create a new version: If data exists on the target server, the restored data will be restored under a new name.
- Preferred media pool: If the data was migrated or replicated and different media pools were used for the process, you can select from the drop-down list of available media pools the source media pool to restore from.
- Used media | barcode: If the data was migrated, the migrated copy is stored to another media. From the drop-down list of available media you can select the source media to restore from.
- Optionally, select the drive number of the drive that will be used to read the data. Typically, you specify the drive if you have configured additional drives and want to use dedicated drives for restores. For details, see the option Create second drive.
- The Interface field shows the SEP sesam Server or RDS with the attached data storage that contains the selected saveset.
- You can specify additional restore settings by clicking the Expert Options button, for example, modify the log level settings, define the pre/post script for the restore, etc. For details, see Restore Overview.
When performing a VM restore, you can also select to automatically start a virtual machine after restore.
Note The Expert Options button for setting advanced restore options is only available in advanced UI mode (formerly expert GUI mode). To use Expert Options, make sure your UI mode is set to advanced. For details, see Selecting UI mode.
After you have set additional restore options, click Next.
- To start your restore immediately, click Start. To save the restore task, click Save.
- If you have mounted a saveset, click OK to unmount it and end 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 monitor the restore progress using the Web UI (Monitoring -> Restores) or view the status in the GUI (Main Selection -> Job State -> Restores). The restore overview provides detailed information on the last run of restore jobs, including task name, status (successful, error, in queue ...), start and stop time of the last backup, data size, throughput, etc. For details, see SEP sesam Web UI or Restores by State in the GUI.
