8.3. Restoring information from backup media
When you restore information, you are taking information that you backed up in the previous section and using one of the restore methods discussed in the following sections.
8.3.1. The tctl command
The tctl command sends subcommands to a streaming tape device, like /dev/rmt0. This command can manipulate tapes easily for data restoration. The general syntax of the tctl command is as follows:
tctl [ -f Device ] [ eof | weof | fsf | bsf | fsr | bsr | rewind | offline | rewoffl | erase | retension | reset | status ] [ Count ]
If you do not specify the Device variable with the -f flag, the TAPE environment variable is used. The most common subcommands are shown in Table 8-2 on page 228.
