Dear All,
I am experiencing a problem at present whereby database restore is failing, quite often only a few minutes into the restore. No failure reason is given, and the query that calls the restore just completes.In the object explorer, the database shows as "restoring" but sys.dm_exec_requests shows no active restore.
the topology of the process is as follows;-
The backup file resides on Server A, a virtual server which runs Attachmate.
Server B triggers the database restore via a SSIS package, which runs an SQL query to start the restore. The extract is being restored to linked Server C.
The database back up is approxmately 15Gb and this restores to an unpacked 70GB on Server C.
I have noted that there seems to be a data transfer limitation on Server A of about 3Mb/Sec, and I have asked our tech team to look into this.
Can anyone suggest what might be happening and how can trace why the extract restore fails but gives no error? My conjecture at the moment is that the data connection is dropping between Server A and Server C, and the restore thinks it is finished, but cannot complete as key information is missing.
Any help gratefully appreciated.
