You seem to be hitting this bug: CSCsg99385

Also why don't you try the workaround from CSCsd39789:

Symptom:

During backup of a system, the BARS log will generate the warning

[Warning] Failed to copy URL Services page from remote machine . Files can be backed up only from backing up server. Backup URL Services page manually.

Conditions

There are 2 conditions that can cause this:

1. the Services URL under enterprise parameters is confiugred using an IP Address.

BARS will attempt a reverse DNS lookup of this IP to get a name and compare that to the local hostname. BARS uses the equivalent of 'nslookup' so DNS resolution is required. BARS does not use default windows name resolution that you get with ping -a . If the reverse DNS lookup returns an FQDN such as myserver.mycompany.com the BARS comparison will fail.

2. the Services URL under enterpriese parameters is configured as a fully qualified domain name.

This warning will be generated if the hostname specified in the Service URL is a fully qualified machine name. The BARS application will use only the local host name when determining if the local host is the location of the Services URL. Backup completes successfully after this warning.

Workaround

For condition 1 above: confiugre DNS server to perform reverse resolution and only return hostname

For condition 2 above: Change the Service URL from a fully qualified host name to the hostname of the server.

Then rerun the backup.
