symantec system recovery point unavailable

[cheewei]

i have discovered on my backup servers that the system recovery is displaying unavailable recovery points even though there present. as well as this the backup jobs have a blue question mark icon which i cant find a explanation for but the backup job is successful, does any one know if there have any solution for this issues?
the version i have is symantec system recovery server 2011 , OS : window 2008R2 64 bit , Backup to NAS.

Thank you ......

Are you running SSR SP2 already ? 

Normally this behavior occurs when you write the backups with a different user than the user that starts the local BESR console, e.g. you login as Administrator and start the BESR console, but the backups are written to a UNC path and the user used to access this location is access_admin.

The SSR is running on SP1 . Do i need to upgraded it to SP2 ? SP2 will solve it .But the backups is running  same credential with the Server Credential.

I'd at least give it a try. Have you tried the thing with the user ?
