BACKUP TO SAMBA NETWORK DRIVE FAILS BUT THE FIRST TIME

[Massimiliano Campagnoli]

I am trying to backup sample database to network drive J:\ which maps
to a SAMBA share.

The first time the backup is successfull but the the next time fails.
I've to delete J:\sample.0 if I want to backup again.

Here is the log:

[C:\]NET USE J: \\LINUXSERVER\BACKUPDB2
The command completed successfully.

[C:\]DB2 BACKUP DATABASE SAMPLE TO J:
