Hi Gazumped and Morticia,
thank you very much for your feedback, I've taken everything into consideration. Here are my comments:
Export time depends on computer performance and each note size significantly. For example, we performed the test in our test lab for Evernote account with ~50.000 of notes, each note is about 5KB and it took ~1 minute only (Windows 8, Intel Core i7-4790, 3.60 GHz, 8GB RAM). Of course, we shouldn't treat this as a constant rule, but I am sure the export takes reasonable time.
May I ask what is the size of your Evernote database? (If you on Windows, just open your Evernote client, then Tools/Options/General tab shows you where your database is located. You can then view that folder in Explorer to get the folder size).
Yes, unfortunately it is a limitation of ENEX export of a whole Evernote database.
After restoring you could mark this notebook as local so it won't sync with Evernote servers, then select those notes that are should be synced and move them to notebooks that are synced with Evernote. Generally speaking, most backup solutions mean restoring large amounts of data in case of emergency. One of Backupery advantages is that all your backup data is stored locally, so you don't need to download it from clouds.
Backupery exports unsynchronized notes too, so the note with the latest modifications will survive (even if it wasn't synchronized with Evernote servers).
It is just an obsolete screenshot on our website. Default settings are every third day.
One more note: actually we are going to add compression of backup directory + we have already implemented deletion of backup duplications.
Does that answer your question? Please let me know.
