When the restore is started, NBU will only look at the Image header to determine media requirements.
So, for a very large backup set, it is normal that all tapes that were used for entire backup will be listed.
When the restore goes active, NBU will go down to image fragment level and request tape mount for relevant fragment.
If all required files/fragments are on the same tape, then no more tape mounts will be required.
What you see is perfectly normal.
makes sense.
but the initial restore not only listed the entire backup set used, it asks them to be loaded in the library and it read them all. however, this second time around, it only loaded 1 media.
as i deleted the restore destination last time because of the failed restore, i was expecting it to start from scratch again. to read in all 7 tapes. so it couldn't have resumed from the failed point (at 200GB) as i have deleted it last time.
this second try it successfully restored 251GB of data using only a single tape! does that mean the 6 other tapes doesn't really contain the data? if it didn't, then why asked for it in the first place?
this is i'm not getting. initially it asks and used 7 tapes and on the second try it only asks and uses 1 tape.
