Thanks again guys.
After this little scare, I'd appreciate a few more details if you have the time though please.
Requirements and assumptions:
I am on Evernote Windows 6.25 and will remain either on this (or possibly the "last good version" in Linux - I imagine probably Windows 6.25, using Wine) until I hear anything positive about "new" Evernote.
I will keep a copy of the 6.25 installation in case Evernote ever forces an update.
I want, if possible, to have a backup taken automatically at regular intervals (possibly keeping the N most recent backups).
The backup will only ever be used in the situation where I irreversibly lose important notes and want to wipe the slate clean (e.g. clear my entire database, uninstall, reinstall and then use the backup to regenerate a recent copy of the database).
If I ever had to do this, I'd like all notebook and notebook-stack structures to be restored, as well as internal-hyperlinks and tags (ENEX sounds like an absolute last resort and would create days of work when restoring)
Questions:
Can Windows Backup backups be used in this way?
...or even some slightly more brute-force approach such as manually copying a folder to an external disk?
How about OneDrive/Google Drive, if set up to only copy one way from my PC to the cloud?
What files/folders exactly should any of the above approaches copy?
Do you have any experience with cloudHQ (specifically, the free version)?
Do you know of any other route through e.g. the IFTTT Evernote plugin?
Thanks for your help! Please don't use your time researching any of this that you don't already know!
There seem to be some older threads on backing up, but links within them saying "this has been explained well in another thread" are dead and take me to the forum home. The info I can find focuses largely on ENEX files and says to avoid OneDrive (I imagine because they assume two-way sync), but I am personally only interested in a doomsday solution (backup, not sync) which will maintain, as a minimum, my notebook and stack structure.
