With archiving file systems, you can configure the archiver to write copies of files to archive media. After files are archived, information about the files can be captured in a recovery point. In the event of a disaster, you can then use the recovery point file to restore the files or the file system itself.
You can restore file systems using any recovery point, including recovery points generated by other file systems, as long as the archived file data from the file system is accessible.
You can also use multiple recovery points to restore files into a single file system. Conversely, you can use a single recovery point to restore file data into multiple file systems. For example, you could restore directory dir1 from recovery point file snapshot1 into file system mysam, and also restore directory dir2 from snapshot2 into the same file system (mysam). You could also restore directory dira from recovery point file snapshot3 into file system sam1 and directory dirb from the same recovery point file (snapshot3) to a different file system, for example sam2.
For information about planning recovery points, see Planning Recovery Points.
To restore a file system if the software version 4 update 6 is installed:
The file system files and directories are displayed in the table.
An index file is created. If the recovery point file was compressed using the compress utility, a new decompressed version of the recovery point file is also created. The original version of the recovery point file remains on the server. Files compressed with gzip do not requiring decompressing.
Note - If the recovery point is a headerless file created using the Sun SAM samfsdump(1M) command with the -H option, the system cannot index the recovery point, and you cannot restore the file system using that recovery point with the SAM-QFS Manager software. For information on restoring data using these files, see the SAM-QFS Troubleshooting wiki.
Navigate through the recovery point by browsing through the files and directories in the table.
Click Filter to limit the items in the table so that only the information that interests you is displayed. Then click Apply to apply the filter criteria. For more information, see Filtering Recovery Point Files.
Type a value in the Maximum Entries field to limit the total number of items that are read from the recovery point file.
By default, the location is the path of the original file or directory, relative to the mount point of the file system. You can specify a different path relative to the mount point, or you can specify an absolute path on any archiving file system.
