The HFS service supports backup over the Oxford eduroam wireless network for desktop/laptop machines. At this time we do not allow access over the OWL, OWL-VISITOR or OWL-VPN wireless networks; if you are using a wireless network other than these, please consult the relevant local IT department regarding whether they permit TSM backup.
Please be clear that wireless networks are not suitable for running full backups or backups of large amounts of data. This is because currently they have considerably less bandwidth than a normal, wired network connection, and the connection is sometimes subject to considerable interference. The practical application for backup over wireless is therefore for backup (or restore) of single, selected, small files and folders. Instructions on how to backup only selected items can be found here - Windows, Mac, Unix, or command line.
For details on configuring eduroam access please see the OUCS eduroam pages.
The key issue when accessing the HFS via wireless is that the performance of wireless is significantly lower than the performance of a wired connection to the University network. For this reason we recommend that the initial full backup to the HFS is carried out over a wired connection and ONLY small incremental backups or backups of a few selected files are carried out over wireless.
Usually, the connection is at least five times slower than a wired University network connection, and backup or restore will therefore take longer to complete. At worst, if the wireless connection suffers a large amount of interference, if you are a large distance from the wireless access point, or if there are many users connected to the same access point, then the speed of the backup could be lower. Approximate times for a wireless backup are given below:
There are a number of problems associated with using wireless which can cause backups to fail or stop. If you experience problems with your connection to the HFS please try using a wired connection first to see if the problem persists. Then see our help and support pages and if necessary contact your local IT support staff. If they are unable to resolve your problem, please email email@example.com.
