View Full Version : Backup strategy

04-29-2008, 09:37 PM
This is not directly a SuperDuper! question (it is relevant to any backup software), but I thought that the folks here have a particular interest and expertise in backup solutions. If I'm out of line in posting a question such as this, please forgive me and feel free to delete the post.

I've been using tower-based machines for years, and I currently have 4 hard drives in my tower. The first drive is my "main drive" which is partitioned into a main drive and a safety clone. The second drive is a periodically made backup (clone) of the main drive. The third drive contains backups made with a different product, and the 4th drive contains a bunch of photos.

I'm moving to an iMac, an all in one machine, and it only has 1 internal drive, and, of course, no room for expansion!

So, the question is what to do. Do I get 3 external drive enclosures? It seems wasteful (of power, of noise, and of time as the often sleeping drives spin up) to keep the external drives turned on all the time. Is there a way to keep them off and only powered on a little bit before the scheduled backup occurs?

Are there better solutions for backing up than just an external enclosure?

I'm looking for good ideas anywhere!

You can eject the externals -- SD! will mount, copy and eject on schedule. Most drives will spin down when ejected, which significantly reduces their power usage.

So, is the way this works is that whenever I reboot the machine, the externals mount and I manually eject them, and then let SD! mount them as needed?

Is there a way to not have the externals mount at startup?

Also, my internals in the tower spin up whenever I wake from sleep. Will the externals do that, too?

Thanks for your response.

I don't think there's a way to prevent the externals mount at startup, no -- at least, no way you'd likely want to use (probably could use some low-level mount descriptions to do it). But once ejected they won't remount until you restart.

I don't think the externals, if not mounted, will spin up.
