- CrashPlan for Home
This article is intended for CrashPlan for Home users. For Code42 CrashPlan and CrashPlan for Small Business documentation, read this page on our enterprise support site.
TrueCrypt creates a file container that can be mounted as a virtual drive for storing encrypted data. CrashPlan can back up TrueCrypt containers, but we do not officially support this use.
Articles about unsupported uses of CrashPlan are intended to offer information to expert, tech-savvy users under specific situations. As with all unsupported uses, you assume the risk if you run into anything unexpected.
Information about products from other manufacturers is intended as a resource to help you get the most out of Code42 products. However, our Customer Champions cannot provide direct assistance for these products. For assistance with products not developed by Code42, contact the product's manufacturer.
Step 1: Add TrueCrypt to your file selection
Add the TrueCrypt container (not the mounted volume, just the file itself) to your file selection.
Note: By default, CrashPlan backs up your entire user folder. If the container is stored within this folder, CrashPlan backs up this container by default.
Step 2: Disable TrueCrypt setting "preserve modification timestamp"
TrueCrypt enables an option by default called preserve modification timestamp of file containers. When enabled, TrueCrypt retains the file timestamp from initial file creation, making it look like the file has never changed. This option must be disabled to allow CrashPlan to back up the changes:
- Open TrueCrypt
- Go to Settings > Preferences
- De-select Preserve modification timestamp of file containers
- Click OK
