Okay, you are using linux as server...

> gbak -B -V -Z -T -user xxx -pas xxx C:\dev\BHA\database\mpanni2.gdb

C:\dev\BHA\database\mpanni2.gbk

How can you backup a linux firebird server with windows local paths?

Further, try not to use .gdb. Use .fdb instead.

> The Windows gbak/server version string:
> gbak: gbak version Firebird-W32-V1.0
> ... version "WI-T1.5.0.3744 Firebird 1.5 Release Candidate 4"

Those do not match.

First, update Firebird to Final/Relase. Don't use Release Candidates.
Second, update you gbak (included in release version). Recent is: gbak
version WI-V1.5.0.4306 Firebird 1.5

Always try using the same versions of db server and gbak.

> The Linux gbak/server version string:
> gbak: gbak version LI-V1.5.0.4290 Firebird 1.5
> ... version "LI-V1.5.0.4290 Firebird 1.5"

Those match.

organize some table (because I delete many records from them).

You should do backups on a regular schedule, you know...
