Compatibility Issue between Backup Server and 3rd-party Storage System

1. Compatibility Issue between Backup Server and
3rd-party Storage System
Article ID: GV10-09-02-12
Release Date: 2/12/2009
Applied to
Backup Server V8.2.0.0 and V8.3.0.0
Backup Viewer V8.2.0.0 and V8.3.0.0
Remote ViewLog
Symptom
Both recording files and log data of a GV-System could be backed up to an external iSCSI
storage system through the Backup Server. After the backup was finished, however, you
could not access the storage system through either Backup Viewer or Remote ViewLog.
Cause
This problem occurred because of a compatibility issue between some 3rd-party iSCSI
storage systems and the Backup Server. When the backup of files begins, two inner
connections are created between the Backup Server and a storage system to transfer log
data and recording files. However, some 3rd-party storage systems only allow one connection
at a time to the host or initiator. Although no errors appear at the Backup Server, the backup is
actually incomplete.
For example, the backup of files to Theus N5200 storage system only includes recording files
without log data. Accessing to the backup files from either Backup Viewer or Remote ViewLog
then fails.

2. Resolution
Most iSCSI storage systems can be established for two inner connections with Backup Server
at the same time. If you encounter the problem of incomplete backup, consult your storage
system manufacturer for details.
This issue will be solved in the near future.
