Much ado about Time Capsule

Sunday, March 2. 2008

A little "much ado about nothing" ... No server class hard disk in Apples Time Capsule. You can find rants about that here (on german) and here (on english).

You don´t really need an enterprise class harddrive in the Time Capsule. The Time Capsule HD should switch off as often as possible to save power. Enterprise HD´s like the Ultrastars are qualified for 24/7 operations. For home use this is nonsensical.

More interesting to me for a backup device is the error rate: 1E15 with the Deskstar 7K1000 (The corresponding Ultrastar has the same bit error rate) means one error every 120 TB. That´s acceptable for such a device. (especiallly when you consider that normal consumer drives delivers such an error every 12 TB). I do not assume they use ZFS in the Capsule ...

My problem with the Time Capsule is the single disk. I saw to many hard disk dying to trust a single hard drive, even enterprise FC high-end ones ...

Don't ask too much from Apple. Innovation takes time. Now that they have "invented" backup, it will probably only be a few more months before they "invent" redundant storage.

*LOL*

But you have to admit, that Time Machine made Backup/Restore really simple.

Only using Time Capsule for your backups really doesn't seem to be the best idea - but as a always running backup device to just recover a accidentally deleted file or to restore your files and settings on a new installed OSX it's IMHO just great.

Well, the normal mode of operation for most home users is no backup at all. Thus time capsule is a good step forward for most home users.

Yeah, TC should have some sort of Wake-On-LAN functionality.
Especially, if you really only use it for backup.
Then, the time-machine application could send a WOL-packet a minute before the backup starts and send it to sleep 30 minutes later, if no other backup is running currently (maybe this can be synchronized via Bonjour - I don't know).
I think I'd buy one right now if it could do that.
