Hello,
I have a full backup of 2357GB that spans over 15 SDLT320 tapes as you
can see in the following output:
mminfo -r volume,savesets,written -q
"!incomplete,savetime>=7/13/2009,savetime<=7/15/2009"
volume #ss written
HIS101 71 163 GB
HIS102 5 7806 MB
HIS103 38 165 GB
HIS104 32 160 GB
HIS106 6 130 GB
HIS112 1 54 GB
HIS113 52 194 GB
HIS114 43 221 GB
HIS115 9 169 GB
HIS125 64 159 GB
HIS126 76 178 GB
HIS127 51 160 GB
HIS128 53 235 GB
HIS129 33 175 GB
HIS130 69 187 GB
I want to clone it to disk but I need to do it in three passes
(because I only have 1TB disk available). So I've used 'mminfo' for
getting the savesets and I've ordered them by media:
mminfo -r ssid -q "!incomplete,savetime>=7/13/2009,savetime<=7/15/2009" -om
4099623839
4133178271
4116401055
4082846624
[...]
3176916744
3160140266
3143403038
3126626360
There are 564 unique savesets (i.e. the savesets that spans over more
than one tape appear only 1 time in the list) so I've decided to split
this list in 3 parts (ss1.txt, ss2.txt and ss3.txt) and execute a:
nsrclone -S -f ss1.txt
but it's SLOOOW (6 hours and it haven't finished yet). For example,
this firs clone of ss1.txt savesets uses HIS126, HIS125, HIS130 and
HIS101 tapes
So, what's the fastest method to clone these savesets? (I've supposed
it could be something that makes the tape read as linear as possible).
Thank you very much.
