TSM client for Windows - vulnerabilities in older versions
IBM have released information regarding some security vulnerabilities in older versions of the TSM client for Windows. If you are running our latest packaged version of the TSM client (6.2.2.0) you already have the fixes.
Although we are not aware of any current exploits for these vulnerabilities we recommend upgrading older versions to the latest version which can be obtained from http://www.oucs.ox.ac.uk/hfs/help/downloading.xml
Information on the vulnerabilities is available at https://www-304.ibm.com/support/docview.wss?uid=swg21457604
New TSM client for Mac OS X
The OUCS packaged TSM client for Mac OSX 10.5 (Leopard) and 10.6 (Snow Leopard) has been updated to version 6.2.2.0. This brings it up to the same level as the client packages for Windows and Linux.
For installation instructions and a download link see http://www.oucs.ox.ac.uk/hfs/help/downloading.xml.
HFS passes the petabyte milestoneThis week the HFS reported holding more than 1PiB of primary copy data online. Thats a one followed by 15 zeros or, perhaps more meaningfully, a million gigabytes. Three copies of all data is held, meaning we now manage over 3PiB. When the service started in 1995, tape media held 10GB per piece. Had tape technology stood still, we would now be managing 300,000 tape volumes rather than the several thousand we do now. So thats progress !
Revised HFS web pagesThe HFS Team has begun releasing a revised, restructured version of our webpages. The main aims of this work are: to bring some of our documentation up to date, to make it easier to navigate and to introduce additional help documentation. Please feel free to let us know if you find any dead links or other errors.
HFS VPN-based backup
The HFS will be offering a backup over VPN pilot service from Monday 2nd August. Further details can be found at:
http://www.oucs.ox.ac.uk/hfs/vpn
This service is intended to meet the needs of those who work outside Oxford (off the University Network) for long periods and who still want to ensure that their data is appropriately secured using Oxford-run facilities.
New TSM client for Mac OS XA new OUCS package of the TSM client is now available for Mac OS X Leopard and Snow Leopard. This upgrades the TSM client to version 6.1.3.2 which provides complete support for OS X Snow Leopard including the new Apple file system compression format (known as HFS+ compression). This is a recommended upgrade for OS X Snow Leopard and Leopard.
HFS feedback form now availableIf you have any comments on existing HFS services, facilities, documentation, or notes on how you feel they could be improved, please fill in the online form at http://www.oucs.ox.ac.uk/hfs/feedback.
Daily Backup Limits IncreasedWe have just brought new faster disk systems fully into production. These allow faster movement of the previous day's backups from disk to three tape copies and as a result, we can now increase the daily backup limits from 50GB/day to 100GB/day for desktops, from 100GB to 200GB for servers and to 300GB for large servers.
New TSM Backup Client for Intel and PPC MacThe latest v5.4 TSM Backup Client now supports both Intel- and PPC-based Mac platforms.
HFS Backup Limits RaisedAs a consequence of the various hardware changes we have made through this summer, we are now able to raise the daily limit on backups from 30GB to 50GB for desktop clients and from 50GB to 100GB for server clients.
HFS Departmental/college Server Backups - Service EnhancementsIn early August a new IBM pSeries server (a p570) was installed and has taken over the departmental/college server backups (OX_HFS_B2 and OX_HFS_B6). On 12 September we plan to start a new TSM server (OX_HFS_B4) and all new small/medium servers will automatically be registered to use it. Existing client usage will be unchanged, although we may later move selected clients over for load balancing purposes.
HFS Backup Service - Registration EnhancementsChanges to the registration for backup services are detailed in a paper which has been sent to ITSS for comment. Main addition is that non-DNS registered hosts will be allowed to register. All traffic will be restricted to the Oxford network. Implementation date for enhanced registration is 12 September 2006, with firewall restrictions introduced on the 11th.
HFS Backup/Archive Service - Service EnhancementsIn early May, 12 additional 3592 tape drives were installed into the robotic tape library. More than 8,000 3590 tapes have since been rewritten to 3592s; each 3592 can hold up to 1TB (more than 10 times the capacity of a 3590). The 3590s retired in August, after 10 years excellent service.
