Question remote backup ?
Scenario.............

MachineA has the tape drive.
Currently using ufsdump to backup MachineA.

ufsdump 0uf /dev/rmt/0n /

Currently using ufsdump on MachineB to MachineA's tape drive (appending to same tape).

ufsdump 0uf MachineA:/dev/rmt/0n /

Is there a way to use ufsdump on MachineA to backup MachineB's filesystem on MachineA's tape drive?

I would like to do it this way because I have two separate crons (one on MachineA, one on MachineB) running backups to the same tape drive and would rather have one cron on MachineA that will do both.

Running on solaris 5.8

Thanks in advance

butc_logs

BUTC_LOGS(5)							AFS File Reference						      BUTC_LOGS(5)

NAME
       butc_logs - Message logs from the Tape Coordinator process

DESCRIPTION
       The Backup System Tape Coordinator (butc) process generates two log files per device, one for error messages and one for actions.

   Error Message Log
       The TE_device_name file logs error messages generated by the Backup System Tape Coordinator that controls the tape device or backup data
       file indicated by device_name.

       As the Tape Coordinator initializes, it creates the file in ASCII format in the /var/lib/openafs/backup directory. If there is an existing
       file, the Tape Coordinator renames it to TE_device_name.old>, overwriting the existing TE_device_name.old> file if it exists.

       For a tape device, the Tape Coordinator derives the variable device_name portion of the filename from the device pathname listed in the
       local /var/lib/openafs/backup/tapeconfig file, by stripping off the initial "/dev/" string and replacing any other slashes in the name with
       underscores. For example, the filename for a device called /dev/rmt/4m is TE_rmt_4m. Similarly, for a backup data file the Tape Coordinator
       strips off the initial slash ("/") and replaces any other slashes in the name with underscores. For example, the filename for a backup data
       file called /var/tmp/FILE is TE_var_tmp_FILE.

       The messages in the file describe the error and warning conditions the Tape Coordinator encounters as it operates. For instance, a message
       can list the volumes that are inaccessible during a dump operation, or warn that the Tape Coordinator is overwriting a tape or backup data
       file. The messages also appear in the /var/lib/openafs/backup/TL_device_name file, which traces most of the Tape Coordinator's actions.

   Action Log
       The TL_device_name file logs the actions performed by the Backup System Tape Coordinator that controls the tape device or backup data file
       indicated by device_name. It also records the same error and warning messages written to the TE_device_name file.

       As the Tape Coordinator initializes, it creates the file in ASCII format in the /var/lib/openafs/backup directory. If there is an existing
       file, the Tape Coordinator renames it to TL_device_name.old, overwriting the existing TL_device_name.old file if it exists.

       For a tape device, the Tape Coordinator derives the variable device_name portion of the filename from the device pathname listed in the
       local /var/lib/openafs/backup/tapeconfig file, by stripping off the initial "/dev/" string and replacing any other slashes in the name with
       underscores. For example, the filename for a device called /dev/rmt/4m is TL_rmt_4m. Similarly, for a backup data file the Tape Coordinator
       strips off the initial slash ("/") and replaces any other slashes in the name with underscores. For example, the filename for a backup data
       file called /var/tmp/FILE is TL_var_tmp_FILE.
