Well,
netbackup is using tar to write and read to the tape. If you not
use multiplexing, and you know what is on what tape, then you can restore
backups without netbackup.
I have come in front of many companies that have 15 years
backups and they try to find a travan tape drive (or other) and the software to
read the tapes.

Hi Mark
Thanks for this. Yes, this is one method, but what about a backup
solution - ie: now 20 years out of date, no media, no server to restore to and
in a format unknown to todays backup systems.
What would you do then? :-)
the client does not seem bothered, and is happy to destroy the
Data. But if you are a banking client or someone that needs access to 20+ yr
Data, then surely your planning has to account for this? Or maybe another
solution?

Simon,
A couple of years ago we retired DLT IV and LTO1 drives, going
to a library with LTO4 drives only.
I used bpimmedia to work out which images were on the old media
then bpduplicate to duplicate all long term retention images that were on
the old DLT IV and LTO1 media to LTO3 or LTO4 tapes.

Morning Guys
Not exactly a problem, but a question.
I started to do work for a small firm that has been removing legacy
old kit and media as its 15+ years out of date (example: PC's acting as
Servers, DDS tape drives, 3M Data Cartridges, (mini ones too!! amnd legacy Unix
systems.
Now, what I was puzzled about is "how would they go about
restoring this Data?", considering most of the Technology has just been
removed / phased out.
It got me thinking that we have 5 - 10+ year retention of Tapes for
NetBackup on LTO1 tapes but no means of loading it, you do not have high hopes
of restoring it. Unless you obtain an LTO1 drive. But say 30 years down the
line..... then what! Chances are, NetBackup may not read it, or worse.... No
NetBackup environment at all ! (Similar to the client who was using their own
standard 1990's backup software that is no longer produced and in a format that
cannot be read!)
So really, curious how people would "protect" those
essential years of Data?
Regards
Simon
