@CapitalGGeek - I would start again using one of the
Folder & File synchronisation tools to maintain a one-way mirror backup.
After the first time, only changes are copied -- as mrbrimi says '
hardly takes any time at all'. I do daily backups on all my data using GoodSynch, the calibre ebook libraries only take a couple of minutes at most.
And as well your calibre library(ies) also take backup your calibre configuration folder. it is where optional plugins and non-library specific settings are kept. If you don't know where that is go to
Preferences->Miscellaneous, where there's a button to open it.
