SAVF
Our backup procedure backs up our libraries to SAVFs and in the early morning copies the SAVFs to tape (with seq.#). This speeds up the backup process so that our overnight shifts are not down for a long period of time. Now my question what would be the fastest way to restore a library that is 6,954,364,928 big (almost 7 gig!) other than restore the savf from tape to a "restore" library and then restoring the objects to the original library. Please help!

Hi,

This is going to depend on how you save from your save files. If you use SAVSAVFDTA then you should be able to restore directly from your tapes, otherwise I’m afraid you’re going to have to restore your SAVF and then restore from the SAVF.

You can use the sequence number to restore the SAVF, that should be quicker than specifying the name of the SAVF. Restore command should go straight to the sequence number instead of checking for a matching name at every tape marker.

Regards,

Martin Gilbert.

    The purpose of SAVSAVFDTA is to put the savefile to tape in the same format that would have resulted if you had saved to tape without the savefile process. For at least some of the recent tape drives, it is faster to save directly to tape than to a savefile. You should run some tests to compare the speeds just in case you've actually been losing time lately. But note that you might run multiple concurrent saves to savefiles where you only have a single tape drive. Perhaps one large library might be saved to tape while other jobs are saving to savefiles.
