Challenge
When attempting to assign an Isolated Network name, the following error occurs:
Network name cannot contains the following symbols: ~`!@#$%^&*+=;'><|?*:"
Cause
Due to a VMware SDK limitation, special characters are not escaped when used in the names of vSphere entities such as port groups.
For this reason, Veeam Backup & Replication prevents the creation of a new network with the characters shown in the error.
Solution
Avoid Using The Unsupported Symbols
Ensure that the Isolated Network Name does not contain any of the characters listed in the error.
~`!@#$%^&*+=;'><|?*:"
Workaround
As a workaround, it is possible to override the charcter limitations within Veeam Backup & Replication by creating the following registry value on the Veeam Backup Server.
Key path: HKEY_LOCAL_MACHINE\SOFTWARE\Veeam\Veeam Backup and Replication
Value name: RestrictedNetworkSymbols
Value type: REG_SZ
Default Value data: ~`!@#$%^&*+=;'><|?*:"
To allow a specific symbol, remove that symbol from the value data.
For example, if you would like to use the "pipe" ( | ) symbol in the network name, set value data to:
~`!@#$%^&*+=;'><?*:"
Note: The change will only apply after restart of Veeam Backup Service. Make sure no jobs or tasks are running prior restart.
More Information
In addition to being unable to create an isolated network with a name containing the listed symbols, existing networks containing those symbols may not appear correctly within the Veeam Backup & Replication software. While it may be possible to create network entities within VMware containing symbols that the VMware SDK is incompatible with, they will not appear correctly when added to Veeam Backup & Replication. Furthermore, it may be possible to add that port group as the production network in the Virtual Lab Properties -> Isolated Network settings. Still, the Surebackup job will not be able to match a port group with a special symbol to the production one resulting in a Sure Backup job failure.
