Hi ,
First off Im not a mac guy I have to help my CEO do a off site back up of his IMAC at home to our office at work. Now He has a time capsule at home doing back up and is there a way I can setup a second one at our office and mirror that back up of the other one ?

Apple offers a free iCloud backup for up to 5 Gig - this should be enough for his important documents.  You can get details here:

the backup on Time Capsule should be a Time Machine based backup. i think this kind of support is computer dependent, which means the backup of iMac at home cannot be used to restore system to the iMac at office.

however, a simple disk clone can do the same thing. see below the instructions to clone the startup disk of home iMac, then bring the cloned disk to your office and use the same method to clone the image to the startup disk of the office iMac.

Just to clarify.. you're not trying to copy or clone the iMac at home onto an iMac in your office... you simply want to keep a 2nd backup of the iMac at your office as a precaution for the user?

The Time Machine backup at his home is a FULL system snapshot with incremental hourly and daily snapshots which allows the iMac to be restored to any point in the previous days, weeks or months.  It also allows files to be rolled-back and recovered if deleted fromcopies stored in these earlier snapshots. Read more on Time Machine here -

To mirror the TimeMachine backup it would most likely be 1.5 to 2 times the size of the HD on his iMac which could easily be several hundred GB and not a simple matter to backup over the Internet.

If you just want to keep an offsite backup of the iMac which could be used to recover the iMac in the event of a disaster then a solution like Carbon Copy Cloner would work -
CCC can create a bootable image of the iMac on an external USB drive or network share (which could be a mounted ftp or network share from your office!!)
It can also do incremental backups once the initial full backup is created.  Alternatively you could backup the iMac to an external USB, keep that in the office and just backup mail, docs, files and music on a day-to-day basis.

There are a few online backup solutions for Mac users such as BackBlaze & CrashPlan -

I think the best way is to use crashplan. This is really a good solution and allows good, fast, secure and scheduled backups. You can backup to the cloud or to another computer (at home)
