Error -1020


Recommended Posts

I am trying to back up information nightly from one lion based mac to another on the same local network. Both the source and destination drives are external firewire 800 drives. Format is GUID, mac OS Extended Journaled. They are each directly connected to an airport extreme which are hard wired to each other.

Is it really an external drive and not a small NAS?

I am trying to back up information nightly from one lion based mac to another on the same local network.

 

So the answer to Lennart's question above is "no, it is not really an external drive; you are correct in that it is in fact a NAS"

 

So the issue turns to how you added the Source to Retrospect, and whether or not that same network share point is being accessed at the same time by users other then Retrospect.

Sadly, I don't really know how to tell or what I should do about it... The last version I used was 6 and I could just drag and drop things. This new version seems much more complicated. I installed the client software on the remote computer and then since they are on the same network, it just showed up in my sources. I chose the folder that I wanted and added to favorites and then made a script to copy the files from one folder to another. How can I guarantee that the share pint will remain stable?

I THINK you mean the source is a volume on a CLIENT computer. (The volume happens to be a Firewire drive on that client).

Or is the other computer acting as a file server and you have the server volume mounted on the desktop of the backup computer?

I thought the Airport Extreme only had a USB port, and accepted only one hard drive.

 

We need a much clearer description of your setup and what you are doing.

 

I quote rhwalker.

Please provide:

(1) complete version number of Retrospect

(2) complete version number of Retrospect Driver Update

(3) complete version number of the OS

(4) complete description of hardware being used.

(5) complete description of the steps you are doing

(6) complete description of the problem

I'll do my best!

 

The main backup computer is a new mac pro running 10.7.3 Retrospect version 9.0.1. It has an external firewire drive which has a folder that is the destination. This computer has an ethernet connection to the LAN. Also on the network is another mac pro running 10.7.2, (needs to stay at this version for the time being), and retrospect client 9.0.0. I ran the copy script with no problem after creating it, but after a few restarts? it doesn't work anymore. Now I get this:

I don't know what driver it is, but this is a very recent install. I'm pretty sure it's up to date.

 

Thanks!

Right, that's (much) more clear.

 

I'm curious about what happens on Tarbox PT 10’s Mac Pro. A sharing violation on scanning?

 

You write "but after a few restarts", what does that mean? Have you restarted Tarbox PT 10’s Mac Pro or the computer that runs the Retrospect engine? Or both?

 

You might want to repair Jughead Digital Audio:
