Time Machine Encryption

Question Time Machine Encryption
An article on the Drobo website dated Updated 06/10/2013 11:24 AM says:

Important! Drobos do not support encryption via Time Machine: serious damage to array may result

Before seeing this I had already enabled encryption on the TM backups to my Drobo5N.

To date I have had no problem backing up to, and restoring from the TM backups. Has this problem been fixed or am I just asking for trouble later?

RE: Time Machine Encryption
hi, this might be more related to full-disk/drive/volume encryption, than a flat file container, but im not sure about time machine

(btw i have XP home SP2, a Drobo v1 with 2x 1TB/2x 1.5TB WD greens, & a bkp Drobo v2 with the same + a DroboShare: unused)
& a DroboS v2 with 3xWD15EADS &2x1TB in DDR mode on win7, & a drobo5D (all usb)
  • btw i did a sustained (write) operation for about 6 hours, and got 13.2MB / sec ...objection? "sustained" :)
    (16.7MB/s on a v2 & 47-96MB/s drobo-s)

RE: Time Machine Encryption
Thanks for your reply, but I don't think your experience applies to my case.

I'm running a late 2013 iMac with Mac OS X 10.10.1 (Yosemite)
I [wrongfully] assumed the phrase "Time Machine" would qualify my query sufficiently. ;-)

While I have full disk encryption enabled on my main drive, my Drobo is network attached with dedicated shares designated for Time Machine use on two computers.

When connecting the share to the Time Machine software, I designated "encrypted backups" which produces an (Mac HFS) encrypted sparsebundle to contain the subsequent backups.

I've been monitoring the process closely and so far have encountered no problems creating, viewing, or restoring from the resultant backups.

RE: Time Machine Encryption
hi tom, thats fair enough,
from what you describe, it seems like your drobo is storing your data within its volume, and that the data /content itself just happens to be encrypted, in which case it should be ok, but lets wait for some mac experts with more knowledge indeed Smile
