Title
File system restore hangs for a very long period on "requesting previous index" before job finall -
Description
A file system restore of files on a remote client machine (of many files or a single file) hangs with "requesting previous index" almost immediately after the job is launched.
The job does not fail but after several hours continues to write and the restore completes many hours later.
The line the restore hangs on is:

The restore may be from a backup of a large number of individual files in the in the original backup and this will cause the index transfer from the Netvault server to the temp directory of the Netvault client to take longer.
In this case however restores of individual files were being successfully carried out from backups of equally large numbers of files on other client machines.

Resolution
- Check there is sufficient space on the client machine for it's ~/netvault/ tmp directory to accommodate the index.
The index is transferred from the Netvault database on the server to the tmp space on the client machine.
- Check Netvault connectivity between the Netvault Server and the client machine being backed up.
A new data channel is established to transport the index and this may be going down or not being correctly established.
- If there is a firewall between the 2 machines check that sufficient ports are open for Netvault and that this port range (including of course port 20031) is configured in:
nvconfigurator->firewall both for the server and the client (see solution 3908).
- Check that a sufficient number of ports has been set for the number of Netvault clients linked to this server (normally at least 7 ports per client is recommended).
- Also check the other points on diagnosing network disconnects mid job in the solution document 3657 such as ensuring the preferred and barred IP address fields are set if there is more than 1 active network card in the machine.
- Try relocating the restore to another machine with the same OS to see if the same problem occurs or it is limited to the one client machine. -
