i have the config file setup correctly, its set to do lan mode. also i can backup the servers if i do it in a command line, so i think i got the vcb proxy working correctly. my arcserve server is the vcb proxy. vmware told me to ignore the certificaticate error.

[dconvery]

Yes, ignore the certificate error. It has nothing to do with the issue you are having. Can you edit config.js and uncomment or add the line LOGLEVEL="6";

This will enable verbose logs. These logs are located in %TEMP% - usually c:\windows\temp

Make sure that you use a double backslash for domain-user settings and your mount location in config.js as well.

I forgot...Attach the logs and someone will look at them.

[cfine]

here's what the two log files say in the temp dirrectory. i might not be reading this right, but it looks like its trying to do a san backup vs the lan

[dconvery]

Right. That is my take as well. did you changethe following in config.js

// TRANSPORT_MODE="san";

to

TRANSPORT_MODE="nbd";

[cfine]

yeah thats how i have the transport mode. i changed it last week once i found out i couldnt do san since my vcb proxy wasnt hooked directly to the san.

i just dont know if i need to run something to get arcserve to change.

arcserve tech support isnt that helpful

[dconvery]

OK...I did a little checking, but not a lot...

I don't think Arcserve uses the scripting built into the VCB Framework. It only uses the virtual disk driver and possibly vcbmounter.exe. Is there a pre-backup script associated with the job when you indicate that it is a VM or is this all GUI?

If it is a GUI and there are no scripts, what you MAY need todo is make your proxy a Arcserve client and run pre and post scripts to call VCB the "old school" way. Check out Duncan's blog post. It deals with Commvault, but the script won't change. -> http://www.yellow-bricks.com/2008/01/30/vcb-backup-all-running-vms/

If it uses pre and post scripts already, check to find which on actually calls vcbmounter and add the "-m nbd" option.

I love my script!

You should be able to use pre backup scripts, like Dave said use my script and backup 'em all from 1 schedule. Works like a charm, I wrote it for commvault, but it should work with every single backup solution out there.

[cfine]

thanks for the info guys. i'll give that a try.

[cfine]

well looks like it was just patch issues with arcserve. guess there tech support couldnt figure that out 3 days ago ?:|

[dconvery]

Ya know....sometimes it just falls doen to a simple patch... I thought that was tech support 101 - what version are you running? Oh...there's a patch for that, you need to download it and install it...then call us back and wait on hold for three more hours...

[cfine]

that was the first question i asked. it works with this version correct?

i might work on the script thing anyway. the backups seem to take awhile and i think its not really offloading it to the proxy server... im seeing high network traffic from the esx server to the proxy the whole time its backing up to tape

[dconvery]

Don't forget to change your mode back in config.js if you changed it to NBD for testing...

[cfine]

my backup proxy doesnt have direct access to the san, so i need to leave it in nbd... right?

[dconvery]

OK...I thought you originally said you needed to use NBD mode. I got

confused about the question about high ESX traffic. NBD mode will back up your VMs over the

network, so you will see high I/O on the SC network. If you do a "-t file" if will copy directly from the ESX to tape on the proxy. If you do a "-t fullvm", it will copy the VMDK and related files to the proxy THEN copy to tape.
