copying large backup files over vpn connection does not work

[Guest Günter Krembsler]

Hello,

 

we have two sites, connected via vpn to our main site.

 

On the remote sites we have a regular, daily 2k3 backup.

Every Friday we want to copy the "friday.bkf" to a share on our main site.

 

copy and xcopy always stopped (this happened on both sites!!!) - even

robocopy has a problem:

Error 64: "The specified network name is no longer available"

(ERROR_NETNAME_DELETED).

 

As we used it this way:

 

Source : d:\backup\

Dest : Z:\

 

Files : Thursday.bkf

 

Options : /V /TEE /COPY:DAT /Z /NP /R:10 /W:30

 

the job restarted. But the created file is invalid.

 

Tried Q325487 without any result. No entries in event logs, helping to solve

the problem.

 

Especially robocopy should be able to handle this problem, as it's

restarting the work.

So i am really confused, why the resulting files are invalid though.

 

Any idea on what i can do to solve the problem?

 

Thanks

 

Günter

Hello Günter,

 

Please post your ip configuration for the machines and the connection for

VPN.

what do you mean with ip-configuration?

 

basic ip is working fine. the servers are members in an ad domain, dns and

routing is working as expected.

vpn is done by two sonicwall appliances on firewall / router level, not with

"internal" ms vpn.

 

do you want me to give you the ip's of the two servers?

Hello Günter,

 

It was just the thought of DNS configuration that causes the problems.

well, if dns is the problem, than it should not be possible to crfeate the

share.

 

but i guess we can reduce the number of causes, as the problem occurs during

the copy process itself.

 

and due to the settings of robocopy - even if the connection brakes down -

it is sucessfully restarted and the result is defective anyway.

 

shouldn't this be the main feature of robocopy, to avoid such problems while

copying large files over slow network connections?
