NIS system support provides backup and recovery for all systems they maintain.

The NSR backup keeps 28 days (4 weekly cycles) of backups. Any file that you have read/write access to can be restored. The procedure is as follows:

  1. cd into the directory where the file existed/exists (this is not required, but easiest for a single file restore).
  2. Run the recover command.
  3. At the recover> prompt, add the file you want to restore using the add command. Other useful commands include dir, ls, ls -l, cd. You're basically in a directory browser, where you add files you want to restore.
  4. The directory browse is of the most recent back up, so if a previously deleted file does not show up in the directory, use the changetime command to set the backup directory browse to a previous time/day. Time is supplied in the format output by the date command (or just issue changetime without a parameter and the current time is displayed and you're prompted for new save time. Use the same time format displayed as current save time. You can just supply the date and time defaults to midnight, 00:00:00)
  5. If you wish to recover the file(s) into a directory that is different than the original directory, issue the relocate command and set the directory where the files will be restored.
  6. When you have added the file(s) that you want to restore, issue the recover command to start the restore. If a tape needs to be mounted, a Big Brother alert is generated and the operations center will mount the tape. Simply wait for recover to return.
  7. One of the more useful commands is versions. You can issue the versions command specifying a file and recover will show which tape save times that the file is available on.
  8. The volumes command show show you what volumes are needed to restore the files.
