NOTE: After I wrote up these instructions and had already restored the file using Carbonite, I read an email from Andrew Shell in response to my query about Fargo back ups and learned that Dropbox automatically does version backups and restores of deleted files. Dave has edited the Fargo Docs article on Fargo and Dropbox with information about how Dropbox backs up files. Dropbox's built-in support for file backups and versioning gives me a deeper appreciation for its use with Fargo.
Yesterday I accidentally deleted all the posts to this site by deleting the high level calendar node in Fargo that contains them. Undo did not restore the node. I quickly exited from Fargo and opened my Dropbox account to find the OPML file had already been saved with the deletion. I also checked the two PCs to which I have Dropbox configured to sync files to, and by then the updated OPML file was already written.
I started looking to see whether Fargo made a backup, it does not, and it doesn't need to given that Dropbox provides backup with versioning. I recently just learned about about Dropbox's backup capabilities.
An alternative is to turn off Auto-save, thus providing a way to close a file, without saving, and re-load it to restore any accidental deletes. Another option is to decrease the frequency of auto saves by increasing the length of time between saves. Keep in mind that if you turn off auto-save that means you have to remember to click Save to save the edits you make to an outline.
If you browse the smallPicture folder in Dropbox you will find a folder named #hosting that may contain several files with an extension of pack. I think these files correspond to your named outlines, and the pack extension suggests it is a container of several files, kind of like a ZIP file. I sent an email to the smallpicture-user Google group asking whether that is a backup, and the response is basically no, it's a container for all the rendered HTML files that are used by FargoPublisher to send to the server hosting the named outline / site.
So, it would seem as though I had lost all of the content for this site, but then I remembered that one of the PCs with which I sync Dropbox to is backed up by Carbonite, which is an application that automatically backs up files and changes to files to a server on the Internet. The synced copy of Dropbox files are backed up by Carbonite, and even better, Carbonite retains several versions of changed files.
I accessed my Carbonite backup, clicked Restore, browsed to the location of the file, right-clicked the worknotes.opml file name and clicked Restored previous versions. I then selected a version with a date/time of before I made the accidental deletion, and restored that file using a different file name.
I wasn't sure whether to restore to the actual file name, so fearing that might mess up the named outline, I selected a different file name. Once it was restored to the smallPicture folder on Dropbox and synced, I opened the restored file along with the "original" Work Notes outline, copied and pasted the calendar node that I accidentally deleted. I then did a File, Render All Pages, and wa-la, my Work Notes blog was back in the state it was prior to the deletion.
I've used Carbonite to several years on my main desktop computer that has copies of my pictures. Carbonite automatically backs up files as it detects edits, and with home user accounts, you pay a flat yearly fee to back up an unlimited amount of data on one computer. You can also get service to backup multiple computers as well as a business account that will backup all the computers of a business. The one caveat of the type of account I have is that it only backs up local drives and not mapped drives to external storage devices.
