Size limit for backups

[hoinz]

Hello,

we have a SAPDB database 7.3 on Win2003, and Legato 7.1.2.
For backups, a database tool writes data to a pipe, and Legato reads and saves them.
All worked fine for several months, but now we get this error:

Analyzing output of NetWorker.
    Have found a completion message in the NetWorker output file 'C:\DOCUME~1\_nsr\LOCALS~1\Temp\temp1139569637-1' in line:
    save: SAPDB:SDB_on_xxx level=full, 10 GB 00:07:20      2 files
    Have found a savetime message in the NetWorker output file 'C:\DOCUME~1\_nsr\LOCALS~1\Temp\temp1139569637-1' in line:
    completed savetime=1139569714
    NetWorker has saved only 10737418240 bytes (the database kernel has saved 10904338432 bytes).
The backup size of database and NetWorker are different.

Note that these 10737418240 bytes are exactly 10GB. All worked fine as long as the database had less then 10GB to save.
Not sure if this is a Legato or SAPDB or perhaps Windows problem.
Any ideas where to look?

regards

Problem solved;
for those who may be interested:

Our backups are good.
The error message is caused by some stupid rounding in the communication between Legato Networker and SAPDB database.
If Networker has saved a bit more than 10GB, it will round this number off to 10GB. But later on, for comparison purposes, these 10GB will be translated to 10737418240 bytes, and comparison will fail.

Those, who have access to SAP's Online Service System, may find more information in SAP note 689611.
There is a workaround suggested: Set some parameter to allow some margin of error.
