11. Endura Decryption Utility

125

Note:

If only one drive is available, confirm that the host has enough
available disk space in /tmp to store the contents of the tape. If you
don’t know the exact amount of data on the tape, make sure the disk
space is large enough to hold the maximum amount of data that can be
stored on the tape. To decrypt data from an LTO-4 tape, make sure you
have 800 GB of space in /tmp. To decrypt data from an LTO-3 tape,
make sure you have 400 GB.

To restore decrypted data, have on hand a system running the backup software used to write
the data to tape.

Decrypting Data: EDU Command Line

Review the command line arguments for EDU.

Arguments

edu –i

drive_w_encryptape

–o

drive_w_blank_tape

–n

[number of keys]

-i /dev/nst0
(indicating the tape drive with the encrypted tape in it)

-o /dev/nst1
(indicating a different full path to a tape drive with a tape with capacity sufficient to hold
decrypted data)

-n [number of keys]

EDU returns with system prompts, requesting the full path and file names of the files
containing the key as well as passwords. Enter the number of keys and press

Enter

on your

keyboard.

If you enter the same value for –i and –o arguments, then EDU decrypts the tape, writes the
decrypted data to local disk, and then asks you to load a tape to store the decrypted data.
