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> |

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 Sent from my iPad On Jul 23, 2013, at 18:55, "Director [via mhVTL - A Linux Virtual Tape Library]" <[hidden email]> wrote:

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. |

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. |

This looks valid... Any chance of 'tar'ing up the virtual media and either uploading to this forum or emailing me directly ? Sent from my iPad On Sep 9, 2013, at 14:20, "paul.jan [via mhVTL - A Linux Virtual Tape Library]" <[hidden email]> wrote:

Many thanks. I'll look at this tomorrow morning (about 14 hrs time) Sent from my iPhone On 09/09/2013, at 15:11, "paul.jan [via mhVTL - A Linux Virtual Tape Library]" <[hidden email]> wrote:

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. Sent from my iPhone On 09/09/2013, at 16:13, "paul.jan [via mhVTL - A Linux Virtual Tape Library]" <[hidden email]> wrote:

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. On Sep 10, 2013 4:13 AM, "Mark Harvey [via mhVTL - A Linux Virtual Tape Library]" <[hidden email]> wrote:

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..
