Nope, the client doesn't have to be defined as a server for this to work.


Note, bpbackup runs in the background unless the "-w" flag is used.  Also,
v4.5 and down, the maximum image size is 1TB so you'll have to send this as
more than one backup set.  (v5.0 the image limit is HUUUUGE!)

Well, you could perform a user-directed backup from the client and specify
the file list each time you run it.  Have this list dynamically generated by
the automated process you speak of and it should take care of the problem.
I think you'll have to add the client as a server to your bp.conf files on
the master & media servers before this will work.

Example (run on client):

bpbackup -c <class> -s <schedule> -f <file list>
The file list is the file that contains the list of files/directories you
want to backup and it is generated each time before the backup runs.  Check
the man page on bpbackup for other options.

Hi to all:

  I have a question. I've been doing some tests but none has given me a 
suitable result for mine problem.

  I'm in charge of a backup platform who does a big number of backups, 
some of those backups are considered 'very sensible'. Here's the 
scenario:

- 1 Master server running NB 4.5 under HP-UX 11
- Some media servers (some on shared storage and some on dedicated 
drives).

I have some servers who does very large backups (>1Tb daily) via an 
export full (the admins of those machine choosed to do an export full 
rather than doing RMAN). And they export all the data on a structure 
like this:

/oracle/T11/sapdata
...
...
...
...
...
/oracle/T11/sapdata

  Since this is an unattended process (both: the export & the backup) I'm 
trying to find a suitable way of getting all the directories where SAP 
exports the data and pulling into the library (the number of directories 
can grow without previous notice) and I need to copy all.

Tried many attempts.

Case 1: Explicit declaration of all directories like....
NEW_STREAM
/oracle/T11/sapdata00
/oracle/T11/sapdata01
...
NEW_STREAM
/oracle/T11/sapdataxx

  This approach is unmanageable because I need to keep an eye over this 
server daily to check if there's any new directory to do backup. But I 
can control on how many jobs is divided the complete job and use two 
drives, take profit of the array of disks and the HBA's.

Case 2: Backup of all directories named sapdata like...
NEW_STREAM
/oracle/T11/sapdata*

  This isn't acceptable, because puts all the copy under one only big job 
and wanted to use the two dedicated drives I have on a Media server for 
this duties.

Case 3: Use expressions to divide and make the backups:
NEW_STREAM
/oracle/T11/sapdata0[0-4]
/oracle/T11/sapdata1[0-4]
NEW_STREAM
/oracle/T11/sapdata0[5-9]
/oracle/T11/sapdata1[5-9]
...
...
...
NEW_STREAM
/oracle/T11/sapdata8[5-9]
/oracle/T11/sapdata9[5-9]

This case is not acceptable, because some directories not exist and the 
software expands those expressions and try to do some jobs and the 
directories doesn't exist (it gaves an Error 71) and shoots over the 
IT/O console, giving scaring the operators by thinking that one or more 
directores are lost.

Any other suggestions for doing this backup without needing to check 
daily the number of directories and modificating the policy when is 
needed?

Best regards,
  Alfonso Correas
