Warning: By switching servers you will have to reupload your entire backup!
I’ve been using CrashPlan to do local backups for over a year on my Macs to other disks, but now with reasonable CrashPlan Central prices ($12/month down to effective $6/mo pre-paid for 4 years for 2-10 computers on the “family” plan) I have decided to give them a shot for my online backups.
More on my backup strategy later, but one issue I noticed with CrashPlan Central was very poor speeds uploading on one of my computers. Three of them uploaded at an average of 10-20 Mbps, but one was stuck at ~1 Mbps. Odd! I even tried everything from the CrashPlan support site on Settings for Faster Backup speeds were still really bad.
I did some digging and found out that the fast computers were using Atlanta based servers (atlb1 and atlb2) and no wonder why those are fast — I’m in Atlanta! The slow one however was using a generically name server (central1) located in another state with much more latency.
Great, I know the problem now but how do I switch servers?
Well, turns out you can assign your box a new machine GUID (a random identifier) and it’ll get assigned to a new home server randomly. I gave it a shot and bam, I ended up on atlb2.
In order to do this you double click the CrashPlan logo (a green house) twice on the main screen and type in the command “guid new”. This will reset your local CrashPlan instance requiring you to set it up as a new computer, losing all your configurations, even local backups. Not only that, you will have to start back over with your initial backup. You have been warned! You’ll want to delete the old instance for your computer on the Destinations tab after you have made a successful backup, too.
Since my switch on the slow box, which also had the most data, I am enjoying super-fast uploads and an estimated backup seed of ~1 week vs 1.5 months. Woohoo!
Update 4/26/2012: In order to check what server you are on, try this:
I just looked through the log files and that info is available in app.log, under the DESTINATIONS section. Look for the “private” variable which should show something like xxxxx.crashplan.com:443
