Centera support for secure delete
Does Centera have any support for performing a 'secure delete' of data when a C-Clip is removed by FPClip_Delete?
By 'secure delete' I mean multiple overwrite passes over the disc sectors that held the associated blob.

Thanks for the info. I had done quick scan through the docs but not for the word shredding!

Hi Alan
The API doesn't have a secure delete call but the administrator can enable secure delete (shredding) on the Centera cluster. Once enabled, all subsequent deletes will have the blob blocks overwritten by a random bit pattern 7 times. Note this overwriting is performed by the Garbage Collection task which is a task that is scheduled by the storage admin. Also enabling shredding will lengthen considerably the time taken for GC to run.
