Both is right. The Upgrade is from v. 1.0 to v 1.5 and from classic to
the superserver. If I go back to the 1.5 classicserver the backup runs
fast again.

One machine is an IBM Server with P4 with 4GB RAM, the other machine was
an AMD Opteron 8 GB DRR RAM.

The OS on the P4 was first SuSE Linux 9.3, then Debian 3.1 Sarge with
2.6 Kernel, on the Opteron only Debian 3.1 Sarge with 2.6 Kernel.

gbak started with "gbak -b -v"

The Backup's are running every night. One time per month a validation
and a garbage collection was done. The database looks good. No error
messages.


Thanks
