Has Kovid committed to maintaining backwards compatibility to his export/import file format over time, i.e. will an export done today be importable into the future - let's say even just 2 years hence.
Library export copies every thing, every time. This can take considerable time for large libraries, even more so if one is exporting it over 'Net, in which case one must also consider the risk of losing the connection when exporting or importing. And if it takes long time, it's London to brick on, it won't get done as often as it ought be done.
Can one easily restore an individual book from a calibre export file? AFAIK the answer is no.
I recommend buying a good quality external HDD, preferable USB 3.0, probably 2-3TB. And use something like SyncBack, SyncToy, FreeFileSync, GoodSync . . . to maintain an incremental mirror image of
all your valuable data including calibre libraries and its configuration folder. An incremental backup only copies changes since last time it was run, and a 'mirror' is an exact copy of the original and it can be used just like the original. And individual items can be restored - eg a cover.jpg that disappeared.
