CrashPlan 3.6.3

Code42 Software has released CrashPlan 3.6.3 with a simplified installation process for new users thanks to the inclusion of the Java Runtime Environment (version 1.7.0_45) when installing on Mac OS X 10.7.3 Lion and later. Previously, you were prompted to install Java separately, now that Apple doesn’t include Java by default. The update also increases the Java heap space allocation to 1024 MB for better performance, ensures that network interface exclusions and wireless network exclusions are properly obeyed, provides more control over CrashPlan’s unlimited version retention, enables those who use the 448-bit encryption + password security scheme to set a challenge question and answer, and updates translations. There’s no need to download CrashPlan 3.6.3 manually, as the app should upgrade automatically in the coming days if it hasn’t already — the version number is displayed prominently in the app’s Settings > Account screen. (Free with a 30-day trial of CrashPlan’s online backup service, 50 MB, release notes)

I'm getting ready to use CrashPlan and I've read through Joe's book, but I'm not quite sure about one thing, and maybe someone here can help. I intend to use a hard drive locally and CrashPlan online, but I need to know if I would have issues if the local hard drive was only mounted overnight.

I don't think there would be any problem there, apart from losing the advantage of constant local backups throughout the day. CrashPlan is good about simply pausing whenever its destinations aren't available or are full or have some other issue.

Does CP keep track of changes while it pauses to wait for its destination drive, or will such changes be missed? I'd like to not have the external drive hooked to my laptop except overnight.

It will catch up when the drive appears; all you'll "miss" is the interim updates. So if you make a change at 10 AM and then another one at 11 AM, you won't be able to revert to the 10 AM change if you only back up at 5 PM.

Another possibility, if you have another Mac, is to put CrashPlan on that, with the external drive, and back up to it all the time, just like CrashPlan Central.

Okay, that's what I thought, but wanted to be sure. Thanks for the help.

For what it's worth, copies of CrashPlan on my network did not auto-update, and that caused some communications difficulties with copies elsewhere that did. I resolved the problem by downloading 3.6.3, uninstalling 3.5.3 using the uninstaller provided on the disk image, restarting, then installing 3.6.3 fresh. No data was harmed in the process, though I did have to log in again after reinstalling.
