Large Filesystem backing up to tape

[meyer8458]

I have a 2TB file system I am trying to backup to tape. I have about 1.5 TB of change each day on this mount point. I have IBM LTO-2's in my L700. The issue is that there is only one directory under the mount point, so I am unable to set up multiple savesets to get more than one stream. These are Oracle RMAN .bus files and their names change daily such as:

/directory/HOT_db444555599674.bus
/directory/HOT_db444555599675.bus
/directory/HOT_db444555599676.bus
and so on.

It would be great if I can dynmically update the saveset list for this client and back up each of these files as a separate saveset stream.

Tape is probably not my best solution for this, but I am stuck with what I have right now. Any help or ideas will be appreciated.

FYI, I am running Networker 6.1.4 and this server is a Storage Node.

If you can extract the names of the files, then you can generate a script to update the savesets:
nsradmin -i update.txt
where update.txt is
---------------------------------------------------------
print type: nsr client; name: <client>; group: <group_name>
update save set: "<file_name>"
quit
----------------------------------------------------------
We use this script for variable database backup, and it works fine.

Correct. What you need is a dynamic script that detects the save sets and splits them into multiple save streams. Probably somebody else can help.

Here is what I wrote. It runs in cron once daily:
#!/usr/bin/ksh
ls -l /fdmsbkup_nfs/hot/pfdms| awk '{print $9}' > /opt/legato/fdms-list
rm /opt/legato/nsrlist.txt
for i in `cat /opt/legato/fdms-list`
do
print "/fdmsbkup_nfs/hot/pfdms/$i," >> /opt/legato/nsrlist.txt
done
cat /opt/legato/list >> /opt/legato/nsrlist.txt

saveset=$(cat /opt/legato/nsrlist.txt)
#print $saveset

sync;sync
echo ". type : NSR client;namesas102;\n
update save set: $saveset;" | nsradmin -s pstb100 -i -
