That's true as long as the damage was done via unlink. However a file being overwritten is another story. That's why regular backups are essential, as you say. > Backups are a highly recommended and mostly orthogonal safety > net. I agree that the two are orthogonal. My concern about nrm and similar tools is that they can instil a false sense of security in naive users. Maybe I'm just paranoid, but paranoia in a sysadmin is no bad thing. > The nrm approach also diverts lots of support requests from the > department backup guru, and lets most users fix their own problems > without any need for help. That depends somewhat on how restores are handled. On many systems the backup appears as a mounted read-only filesystem mirroring the live system, in which case restoring is as simple as the "cp .gone/..." example you give. That's how I do it at least. poc -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
