From: Gavin on 31 Mar 2010 17:39 Hi, Does anyone know the maximum amount of Macs that can have backups run onto a single time capsule? Would 3 on a 2TB work out OK. -- Gavin. ACSP 10.5 http://www.stoof.co.uk http://www.twitter.com/gavin_wilby

As many as you like, depending on data quantity. >Would 3 on a 2TB work out OK. Maybe. Up until a week ago I had four Macs backing up onto a 300gig disk, but then I traded up a Mini for an iMac and had to squeeze a fifth on there - so I put a 1Tb disk in place (USB enclosure off an Airport Extreme). How much do you want to back up? How much changes each day? Mine: Mini 1 - media player, with media hosted on the NAS. 20gig backups with a year history. Mini 2 - ex personal machine, 70gig with a year history. MacBook Pro - 120gig with two year history. Air - 50gig with a year history. iMac - 50gig with a year history migrated from the Mini. But I exclude virtual machine files, my /Applications/Games folders, Entourage database, and a few other things that are rather large and pointless to backup.

Cheers Jamie - its not for me actually, but for a friend of a friend. They are "light" users, and the data will mainly be photos, itunes, and the odd document and email. Nothing too big at all. How does one split the TC, so that each TM knows where to back up? Do you set an account through the airport utility to each user? -- Gavin.

Should be plenty of room then. My main machine is pretty much that, and as you see only got to 70gig in a year. Oh - I do exclude my iTunes folder, since my audio files all live on the NAS. That could add a fair chunk. >How does one split the TC, so that each TM knows where to back up? Do >you set an account through the airport utility to each user? No need, it just works. Each machine makes its own disk image file on the Time Capsule to save into. Cheers - Jaimie -- #include "clue.h"

It depends on the total size of the data to be backed up (must be less than the capacity of the Time Capsule, with a fairly big safety margin), and the size of the incremental backups (which depends on what is changing on each computer between backups). If one computer has significantly more data changing than the others, it will end up occupying the lion's share of the Time Capsule. Once the Time Capsule fills up, you won't be able to add any more computers without manually intervention (at least deleting lots of old backups, possibly going as far as deleting all backups for at least one computer). Try to avoid using Time Machine to back up enormous files that change frequently, e.g. Entourage database or Virtual Machine hard disk images. -- David Empson dempson(a)actrix.gen.nz |
