I use Sessions to keep track of browsing sessions in Safari. I was having some trouble with invalid cookies and I cleared my web history. Now all of my saved Sessions are gone. Is there any way to recover the data? Where does Sessions store it's data? I may have a backup.

If you go to Sessions "Help" (in the gear menu), there are two questions relevant to your issue:

Why did my saved sessions disappear when I reset Safari or cleared its history?

The option to remove website data, available when either resetting Safari or clearing its history, will delete extension data without warning. Some third-party cache cleaners may do the same. It is recommended to take care when using these tools, as any data so deleted can only be recovered from a backup.

and more importantly for you:

How do I recover Sessions data from a Time Machine or other backup?

If you are familiar with the command line, try using the sessions-export script. This is the recommended procedure. Alternatively, it is possible to physically replace the database file with a backup. The .db file under the directory ~/Library/Safari/Databases/safari-extension_yoo.david.sessions-deub45nr9t_0/ can be replaced by a recovered file if the latter is renamed to match the file it replaces.

So, if you have a backup, it should be as easy as a copy and maybe a rename.

Sessions seems to store its data in the browser's javascript database which, per this stackoverflow posting, is in ~/Library/Safari/Databases.

In fact, I see a directory in mine called something like safari-extension_yoo.david.sessions-<random number>. The contents appear to be an SQLite database:

$ file *
0000000000000001.db:     SQLite 3.x database, last written using SQLite version 3008010
0000000000000001.db-shm: data
0000000000000001.db-wal: SQLite Write-Ahead Log, version 3007000

Using sqlite3 per the instructions here and here, I can see what looks to be interesting data:

$ sqlite3 *.db
SQLite version 3.16.0 2016-11-04 19:09:39
Enter ".help" for usage hints.
