The autoclone worked perfectly. I was on the wrong track.
The problem is with the nsrstage :
If you did not specify ssid/cloneid when staging, only
1 instance of the SSID is kept, the other ones are lost.
Look :
i take a backup on an AdvFile device and clone it twice.
(I don't care about cloneid to take the clone)
C:\>mminfo -q "ssid=2924977175" -o t -r
ssid,cloneid,client,totalsize,sscreate,volume
ssid clone id client total created volume
2924977175 1213701143 networker 3545 MB 17/06/2008 DISK02

2924977175 1213702926 networker 3545 MB 17/06/2008 LTO088
At this stage, I have 4(3) SSID Copies :
2(1) on AdvFile device,
2 on tapes : one on LTO061, one on LTO088. Normal, 2 copies
of a SSID cannot reside on a same media.
Now, I stage my File device in order to reclaim space.
If you DO JUST SPECIFY SSID when staging :
C:\>nsrstage -m -b LTO3 -S 2924977175
6330:nsrstage: Cannot access volume LTO088, please mount the volume or
verify its label.
6365:nsrstage: Space can only be recovered from adv_file and file type
devices.
C:\>mminfo -q "ssid=2924977175" -o t -r
ssid,cloneid,client,totalsize,sscreate,volume
ssid clone id client total created volume
2924977175 1213706164 networker 3545 MB 17/06/2008 LTO254
-> you lost copy of LTO061, LTO088 and just keep 1 on tape.
IF YOU SPECIFY SSID/CLONEID when staging :
C:\>nsrstage -m -b LTO3 -S 2924977175/1213701142
C:\>mminfo -q "ssid=2924977175" -o t -r
ssid,cloneid,client,totalsize,sscreate,volume
ssid clone id client total created volume

Hello,
Trying to understand , i don't recall , giving ssid list when auto
cloning is enabled, would it be Networker that created this problem via
auto clone ? or was it a manual clone operations ?
Perhaps i misunderstood the remedy here ?
Thanks

[Networker] SOLVED: NSR74, Savegrp autoclone not cloning when reading from
Afv_File ?
Sharing the info with you, I located and fixed
the problem :
Clones were effectively well launched at the end
of the savegroup completion. BUT ...
The problem came from nsrstage when staging
the disk devices : as no cloneid was specified in
list of SSID nsrstage should stage, it results
in Legato to move "all" instances of the SSIDs
to the stage target pool (reading only 1 effectively)
and invalidating all other SSID copies (removing entry
from mediadb so losing tracks of the cloned copies also).
Sample of lost backups

Updating nsrstage script with ssid/cloneid just move the right
SSID copy to its new pool.
Something to remember !!
Thanks to all who responded.
