Error
HP Data Protector 9.08
Backup to StoreOnce catalyst of hpux objects
Issue:Restore attempt of hpux filesystem objects fails with :
[Major] From: RMA@abcd "DC_Unix_xyz[GW 2564:0:532443951933574231]" Time: 3/04/2017 13:53:41

[Major] From: RMA@abcd "DC_Unix_xyz [GW 2564:0:532443951933574231]" Time: 3/04/2017 13:53:41
[90:52] \\storeonce1\DC_Unix\3347870a_58ce56af_1020_1f18
Cannot read from device (JSONizer error: CRC failure)
The same backup was also copied to tape , restoring of the same object from tape went fine.
Also after export/import of the b2d media ,restore went fine.
Cause
Cause: The backup was taken with log level "LOG FILES" ( default is "LOG ALL")
It seems that StoreOnce requires LOG_ALL to record proper per-item offsets to allow correct positioning, as jsonizer does not have catalog segments per set.
This is not documented
Fix
This behaviour will be documented :
here is the example how Online Help will be updated :
