July 2009 Archives

At home we have a Time Capsule for our laptops (and a mac mini) to automatically backup a few times a day. We got it shortly after it was released; and have been happy with it since whatever Leopard and firmware update it was that made backups work reliably. Between backups of Vani’s old MacBook, her new 13” MBP (very shiny) and my MBP (with a newly upgraded 500GB disk) the 1TB disk finally got filled up. I tried deleting some old backups; but basically there’s just too much data.

time_capsule_disk.pngFortunately the wizard making hard drives have come up with magical 2TB disks recently. That’s about 2,000,000 megabytes.

(Update summer 2010: Last summer a 2TB disk cost more than $200; now it’s getting really close to $100!) I like Western Digital disks because their warranty process is really easy, at least in the United States. I don’t know if they break more or less than other disks; but all disks eventually break.

To replace the disk I followed the hardmac.com instructions with a few modifications.

Because our Time Capsule have been running for a year and a half, the glue on the “rubber protection” had mostly hardened and it was hard getting the rubber off without tearing it completely to pieces. Keep a knife handy.

I didn’t want to start over on our backups, so I put the new disk into the TC; started it up and formatted the disk with the Airport Utility. I didn’t bother reassembling it for this stage, because after formatting I removed the disk again and put it (and the old disk) into external enclosures and used Super Duper to copy the old disk to the new. You could also should use rsync (/usr/bin/rsync -avPE "/Volumes/Old TC" "/Volumes/New TC"), because Super Duper will miss some “hidden” files that Time Machine needs to operate.

It’s still copying (estimated time to completion: 16 hours, yikes!), so I haven’t put it back together yet; I’ll update the post when I have and checked that the backups resumed as expected. (Update: Yup, the rsync worked fine - after putting the drive back everything was in place the same as on the old drive; except with twice the space).

Two “AP*” partitions will show up as well for each disk when you plug them in; just ignore or unmount those.

Footnote

We use Time Machine Editor to configure Time Machine to only run every N hours instead of every hour which is a bit much.

Excellent OS X VPN client

viscosity.pngAt both Solfo and over at perl.org we have the non-public network services (basically everything that’s not http, smtp or http) suitably locked down in a private network. At Solfo we have an OpenVPN server for logging into the private network. It’s great that it’s open source, works over both TCP and UDP (for respectively goofy firewall setups and faster, more reliable connections) and best of all, there’s great OS X GUI for OpenVPN: Viscosity VPN.

Traveling and needing to get on our network and being on various goofy corporate and hotel networks (and wanting to watch Netflix outside the US reminded me how excellent it is.

We’ve used Viscosity VPN since it was in beta and I can’t recommend it enough. It’s as reliable as can be, the support is excellent, it looks good and while it’s not free it’s super cheap, licenses start at $9 each. We bought more than twice as many licenses as we needed just because I felt bad not paying more!

Now if only the iPhone supported OpenVPN, too, so we could put more services on the private network without having to setup another VPN service…
