Backing up your Series Reminder data is a premium feature only.
Creating a backup of your Series Reminder data is easy. Log into your account and under the Tools menu select Data Backup and then click the button with the format you desire. A file will download that includes the date of the backup in the filename.
The backup is available in 2 formats, CSV and JSON. For each series in your favorites list the following information will be included in the backup.
Please take a backup of your Series Reminder data before doing an import from another service. If something goes wrong in the import I will not be able to recover your data unless you have a backup file.
Automatic monthly backups are not yet available. I am a one man show building this site and need to focus my energy on the features that most people are asking for. I do plan on eventually building some kind of automatic monthly backups to either a Google Drive or Email. If you would like this feature please contact me and let me know.
