Simulating NetBackup Vault

[Director]

Hi,

We are new to MHVTL and we have found it a great tool to simulate changes in the netbackup environment before actually implementing it to prod.

We want to simulate the following:
1. Backup to tape
2. Run vault policy to duplicate, create catalog and eject the tapes
3. send to tapes to offsite location
4. inject tapes to the library in the offsite location
5. recover catalog to the DR site
6. restore Backup

Is there someone who has already tried this? Is this possible using MHVTL>

[Mark Harvey]

All of the above is possible (and more)..

To simulate a library MAP, use 'vtlcmd xx list|open|close|empty map'

Copy the virtual media /opt/mhvtl/<barcode> to the offsite server.
Use 'vtlcmd XX open|load|close map' at the other end to simulate opening, inserting, closing MAP port

Hi Mark,

I'm using Netbackup to simulate VTL. I tried to copy the media /opt/mhvtl/barcode/ to another location of tape library /opt/mhvtl/90 and scan the tape in Netbackup. But the media doesn't appear.

What are the steps to move the media to another libarary? I'm currently using mhvtl 1.4.8-c896449

Thanks.

[Mark Harvey]

vtlcmd 90 open map

vtlcmd 90 load map <barcode>

vtlcmd 90 close map

vmupdate -rt tld -rn 0 -empty_map -use_barcode_rules

Thanks Mark it works. :-)

Hi Mark,

I successfully moved the tape to the other library but the problem is when i tried to import the tape it says "cannot read media header, may not be Netbackup media or is corrupted"

Here's the steps i did:

Eject the tape from Netbackup console
copy /opt/mhvtl/<barcode>
vtlcmd # open, load and open command
vmupdate -rt tld -rn 0 -media_empty -update_barcode_rules
import the tape (failed)

Is there any steps i miss?

Thanks.

[Mark Harvey]

Can you supply the output of "dump_tape -f <barcode>"

On both source & destination copy pls

This looks valid...

Any chance of 'tar'ing up the virtual media and either uploading to this forum or emailing me directly ?

The phase I & II import were successful. As the image contained bits of a windows file system, is this backup via a windows media server ? If so, how is it connected to the mhVTL ?

Can you supply bptm log (verbose 5) during the import.

Hi Mark,

I sucessfully import and restore the tape yesterday. I just found some technote on symantec regarding nbrbutil command. Im still figuring out how this command works.

Thanks.

Hi Mark,

I sucessfully import and restore the tape yesterday. I just found some technote on symantec regarding nbrbutil command. Im still figuring out how this command works.

Good news regarding successful import & restore.
I would strongly recommend reviewing your NetBackup config and defining "Media ID generation rule" as per best practice.

'nbrbutil' is one of those dangerous commands..

If at all possible - don't use (except the "-dump" option) while backups/restores/duplications/(anything really) is going on.
And if the system is idle - it's safer to restart daemons anyway..
