[gpfsug-discuss] backup and disaster recovery solutions

[Jaime Pinto]

I heard as recently as last Friday from IBM support/vendors/developers  
of GPFS/TSM/HSM that the newest release of Spectrum Protect (7.11)  
offers a GUI interface that is user centric, and will allow for  
unprivileged users to restore their own material via a newer WebGUI  
(one that also works with Firefox, Chrome and on linux, not only IE on  
Windows). Users may authenticate via AD or LDAP, and traverse only  
what they would be allowed to via linux permissions and ACLs.
