BACKUP
Four Distinct BACKUP Command Operations
You can use the BACKUP command to do the following four operations:
• Back up data into a saveset or subset file.
• Verify the accuracy of your backed-up data.
• Get a directory of backed-up data.
• Restore backed-up data.
Each of these operations can be done separately, though the verification operation
can also be done with a backup or restore operation. Table 1 lists all the valid
BACKUP command option combinations for these backup operations.

Backing Up Files
If you supply no options, BUP assumes you want to back up a file(s) into a saveset.
This procedure allows you to back up all files on a device without copying empty
blocks.
