Restoring tape files...
Hi all,

I have kinda inherited this problem, but was wondering if anyone else had any ideas.

Currently all our backup rentention periods are set to 2 weeks, so that we can cycle through tapes (save money etc...). Anyhow the guys next door in IT, decided one day long long ago, that it would be a good idea to do monthly backups. Unfortunatley, they didn't tell us this, and so it has now become a problem.

My question is this. Does anyone know of a way to well, essentially by-pass veritas NBU on a vertias volume managed system, and restore things from tape. I know that I can do this from a VXRESTORE, however its an oracle rman backupset that I am looking to restore and normal file system and I didn't use a vxdump in the first place (well I prosume NBU didn't anyhow).

From an OS point of view under Solaris I managed to find some utilities TCOPY and MT. MT doesn't seem to allow me to do this. However TCOPY seems like a good solution, however, it will only copy from tape to a dir, I prosume the entire tape, and being that we don't really have systems with a 200gig + mount point at the moment, I don't fancy trying it.

Has anyone got any other ideas for something that I use? Ideally I would like to be able to mount the tape and see whats on it, and decided what to restore myself.

thanks,

Mark.

read_tape

READ_TAPE(8)						       AFS Command Reference						      READ_TAPE(8)

NAME

       read_tape - Reads volume dumps from a backup tape to a file

SYNOPSIS

       read_tape -tape <tape device>
	  -restore <# of volumes to restore>
	  -skip <# of volumes to skip>
	  -file <filename> [-scan] [-noask] [-label]
	  [-vheaders] [-verbose] [-help]

DESCRIPTION

       read_tape reads an OpenAFS backup tape and prompts for each dump file to save.  This command does not require any OpenAFS infrastructure.
       This command does not need an OpenAFS client or server to be available, which is not the case with the backup(8) command.

       The dump files will be named for the Read/Write name of the volume restored.  After saving each dump file, vos restore or restorevol can be
       used to restore the volume into AFS and non-AFS space respectively.

       read_tape reads the tape while skipping the specified number of volumes.  After that, it restores the specified number of volumes.
       read_tape doesn't rewind the tape so that it may be used multiple times in succession.

OPTIONS

       -tape <tape device>
	   Specifies the tape device from which to restore.

       -restore <# of volumes to restore>
	   Specifies the number of volumes to restore from tape.

       -skip <# of volumes to skip>
	   Specifies the number of volumes to skip before starting the restore.

       -file <filename>
	   Specifies an alternate name for the restored volume dump file rather than the default of the volume name.

       -scan
	   Scans the tape.

       -noask
	   Doesn't prompt for each volume.

       -label
	   Displays the full dump label.

       -vheaders
	   Displays the full volume headers.

       -verbose
	   Produces on the standard output stream a detailed trace of the command's execution.	If this argument is omitted, only warnings and
	   error messages appear.

       -help
	   Prints the online help for this command. All other valid options are ignored.

EXAMPLES

       The following command will read the third through fifth volumes from the tape device /dev/tape without prompting:

	  % read_tape -tape /dev/tape -skip 2 -restore 3 -noask

PRIVILEGE REQUIRED

       The issuer must have access to read and write to the specified tape device.
