Recovering data from an old tape
I tried searching the forums but didn't see anything recent. We rebuilt our Networker server about 6 months ago and we didn't convert over the indexes. Now I need to do a restore from a tape that's a year old that was backed up on the old system. I ordered the tapes from our offsite storage and won't have them until tomorrow so I thought I'd do some research first. Some of the older posts I saw mentioned doing a scanner -i \\.\tape0 or an mminfo command to read the data but those posts were 3-6 years old.
I was hoping I would just be able to load the tapes into our library, right click them and do an inventory to get them into the index, but now I'm second guessing myself after seeing the older posts. Is there a recomended procedure or documentation on doing a restore of this nature? It doesn't seem that it would be that uncommon but I haven't been able to find anything that seems current.
We're running Networker 7.62 on a Windows 2008 R2 server. The backup from a year ago was done on a Networker 7.6 server.

1- For a browsable recovery (using winworkr GUI) you need to rebuild both the media database entries, and the client file index entries. This will take longer to scan.
scanner -i device_name
Example: scanner -i \\.\Tape0
2- If a browsable recovery is not necessary and a save set recovery will sufficent, it is quicker to scan entries into only the media database.
scanner -m device_name
After that you will be able to perform either browsable or save set recovery.
Hope this helps you.
Thanks,

Hi all, I could help me to make a recovery from tape? the program I'm using is the EMC NetWorker (the tape has already been inserted) I would like your support.
thanks.
I have always done since the "recovery" option but I am informed that since that option is only recovered from backup hard disk and not tape.

This statement is simply wrong - NW will not care about the backup media at all.
Just use mminfo and verify a tape save set, then run the recover wizard and restore it to a temp pathname.
