Restoring TAR tapes
TAR is an older method for storing files on tape, often used when archiving
using a Linux or Cache-A system.
YoYotta LTFS and Automation can read existing TAR archives from all drives LTO-1 to LTO-8
Some tapes described as TAR are proprietary and cannot be read.
Load the tape
When the tape is loaded into the LTO drive YoYotta will think that it is blank. Ignore the format panel and open the LTFS panel. Then click on the cogwheel in the bottom right.
Now click the Drive 1 button to restore the tape. Then choose a location, YoYotta will restore all the files from the tape to that location.
While restoring you will see status in the YoYotta log panel. When complete the files will be in the restore folder ready for use. You can use YoYotta to copy them back to an LTFS tape.
YoYotta uses common TAR block sizes to auto detect the format. If the restore does not work, then turn on the TAR test button and try again. This will try more block sizes. If this still does not work, then the tape is probably not a TAR tape and might be some proprietary format.
macOS 10.13 or newer System Security
The first time you read TAR tapes with YoYotta on a new High Sierra system, you will need to approve YoYotta System Software. Also new installs of system software from ATTO, OSXFUSE (developer is Benjamin Fleischer) and other drivers may need approval.
You will see a message saying System Extension Blocked
Open the Security & Privacy page in Apple System Preferences, unlock the padlock and click Allow to enable the System software to load.
You must click the Allow button directly on the Mac, clicking using remote screen sharing will not work.
If the Allow button is not shown then reboot your Mac and check the Security & Privacy page again.
