i've tried the following setup first:
- Time Machine backs up my Boxcryptor.bc folder (plase note, folder and not disk)
- I am doing my usual stuff, adding/removing files, etc.
- Then "ohh sh..." :), i've removed half of my very important files, time to restore from backups.
- Open Time Machine, locate the correct version of Boxcryptor.bc folder, just before removing and restore it to some convenient location
- Now if i want to restore all files, i can just remove the bad Boxcryptor.bc folder and use the restored one, but if i want to restore just some files, i would mount the restored folder, copy the files i want out of Boxcryptor disk to some tmp location, then unmount the disk and mount my working folder. Then copy the restored files to the disk, they get encrypted again, and you can remove the ones in the tmp location. Now you are ready to go, with your files restored.
My second setup, with restoring individual files and making Time Machine browse the Boxcryptor folder:
- Lets say we have Boxcryptor.bc folder. Now Time Machine back-ups it, but it won't browse into the bundle.
- To make TM browse it, we need to do the following: Unmount Boxcryptor disk, go to the Boxcryptor.bc folder, right-click on it and choose Get Info, then in the name input remove the .bc extension. After this operation our folder will be called just Boxcryptor, and you are able to browse it as any other folders, but files at this location are in the encrypted form.
- Now we need to re-add this folder to Boxcryptor and we have a working Boxcryptor disk again.
- We do our work as usual, TM backups everything, now it's time to restore.
- Open TM, locate the Boxcryptor folder, browse it, etc, everything as usual.
- Find and restore your file/files, to the Boxcryptor folder, not the mounted disk. (Actually i would recommend to unmount the Boxcryptor disk before doing restores, as it most probably won't pick up the new files, and you'll need to remount anyways).
- Mount your Boxcryptor disk and your new files should be at the restored location, working fine as before.
!!!! Please note, that in the case of the second setup, you need to be very careful what and how you restore. Your restored files should be encrypted with the same password and settings as your drive. If you've changed your password in between the backups, you might run into problems. In this case i would recommend to use the first setup, with restoring all folder at once, mounting it, restoring the files and copying it to your current working BC disk for encryption,etc.
Also, in the case of the second setup, if you use filename encryption its basically impossible to see which files you want to restore.
