Google Drive Backup
To create a backup in Google Drive, see How do I create a backup in Google Drive?
Squid 0.2.3 introduced a new premium feature (in-app purchase) called Cloud Backup that enables you to backup your notes to cloud storage providers like Dropbox and Box.
With the Cloud Backup in-app purchase, you can backup all your notes and save them to a specific device folder in Dropbox or Box. Then, you can restore a particular backup for a device (or on another device) if you have performed a factory reset, uninstalled the app, or deleted notes you didn't mean to. When you restore a backup, you are restoring all your notes at once to the previous state. You can setup a backup interval to keep your backup in Dropbox and/or Box up-to-date.
In addition, you can export all your notes as PDFs to Dropbox and Box either manually or at a set interval as well. This will keep a copy of all your notes available on any device that can view PDFs and has access to your Dropbox/Box account.
Using 'adb backup'
Starting with Android 4.0 (Ice Cream Sandwich), you can backup applications and their data using the
adb backup command. To do this you must have the
adb tool (Android Debug Bridge) included with the Android SDK. You can backup Squid with the command
adb backup -f <backupFilename> -apk com.steadfastinnovation.android.projectpapyrus
and restore Squid with the command
adb restore <backupFilename>

Manually backup Squid data (root users only)
If you have root access on your device, you can make a copy of the files listed in this article, based on the version of Squid you are running. Restoring these files after re-installing Squid should restore all your notes (although this is not guaranteed). Note that if you overwrite an existing database file with a backup, any notes stored in the database being replaced will be lost.
