My client has just rung me to say that Retrospect is requesting a new tape a quick inspection (over the phone via my client) of the original tape in the scheduled backup set revealed that it has used 33 Gig. I will have to go investigate this but could someone who knows please tell me if I need to have software compression turned on to get 66 Gig out of the tape or is there something else making Retrospect ask for another tape.

Obviously this consumes more tape than if all data records were written contiguously without record gaps. Doug, My understanding is that the VXA drive does packet writes and has a variable speed writing mechanism and thus has much less of a problem with inter-record gaps (gaps of about 100k per pause with capacity turned on with about a 10% loss in speed) (I'll Bcc: Ecrix tech support on this just in case I have the info wrong.) -- -- [EMAIL PROTECTED] Ben Liberman -- -- -- To subscribe:[EMAIL PROTECTED] To unsubscribe: [EMAIL PROTECTED] Archives:http://list.working-dogs.com/lists/retro-talk/ Search: http://www.mail-archive.com/retro-talk%40latchkey.com/ For urgent issues, please contact Dantz technical support directly at [EMAIL PROTECTED] or 925.253.3050.

Re: Firmware for Yamaha 6416
I'm using Retrospect Express with a Yamaha CDRW 6416 with the t.0d firmware that was made available as a beta. Now Yamaha has posted a new firmware update 1.0d.

Re: Powerbook dials internet once an hour?
I'm coming late to the discussion so this may have already been covered. If it's on the same network as the backup server, why not just change the communications protocol for the Powerbook client from IP to Appletalk? It would be really nice if the powerbook could be set to automatically use the dial-up TCP/IP config during the day so the user can get to the internet, then switch to ethernet at night to allow network backup. Can Location manager do that? I've found that the sky's the limit when it comes to Location Manager and AppleScript, so I'm sure it is possible to automate this process. How? I'm not the person to ask that... WISH LIST ITEM: Put an "advanced prefs" section in the retro client, where you can force it not to do those lookups at certain times of day. Or let this be administered at the server. I've logged your suggestion.
