How to Backup and Restore Your Data in Anki

Understanding Anki Backups

As you dive into the world of Anki, an invaluable flashcard software for learning, it's essential to understand the importance of backing up your data and what's included in these backups. This foundational knowledge will help ensure that your hard work and progress are never lost.

Importance of Backing Up

Backing up your Anki data is a critical habit to safeguard your flashcards, study progress, and customizations. You've invested time and effort in creating your decks, tailoring your study sessions, and refining your learning process. Protecting this data helps to prevent loss due to unforeseen events like device failure, data corruption, or accidental deletions. By regularly backing up your Anki data, you ensure that you can quickly recover your learning environment to its most recent state, providing peace of mind and continuity in your studies.

What's Included in Backups

When you back up your Anki data, it's important to know what is being saved. Anki's automatic backups include your card data, such as the text on cards and scheduling information, ensuring that your learning progress and statistics are preserved. However, these backups do not include media files like sounds or images. To fully protect your data, it's recommended to perform manual backups in addition to relying on automatic backups. Manual backups can be stored off your local device, providing an extra layer of security in case your device is compromised.

Anki automatically creates a backup of your collection every time you close the software or sync, with the default setting to keep the last 30 backups. AnkiMobile also performs backups at fixed intervals and before syncing. To maximize data safety, consider exporting your Anki collection regularly, which includes both scheduling and media files. This approach aligns with the recommended backup strategy of keeping three copies of your data: two locally (on different devices or mediums) and one off-site (such as cloud storage).

For comprehensive protection, create a full manual backup of your entire Anki folder. This includes the 'collection.anki2' file along with all media and plugin files. Such a backup ensures that all your card data, media files, and plugins are securely saved and can be restored if needed.

Understanding how to backup and restore Anki data is just the beginning.

Automatic vs. Manual Backups

Protecting your Anki data through regular backups is essential to ensure that your hard work isn't lost due to unforeseen circumstances like device failure or data corruption. Anki offers two primary methods for backing up your data: automatic backups and manual backups.

Setting Up Automatic Backups

Anki simplifies the backup process through automatic backups. According to the Anki Manual, Anki will create automatic backups of your card data, including text on cards and scheduling information. However, these do not include media files like sounds or images. Automatic backups are created every time you close Anki or sync, and by default, Anki stores up to 30 backups.

To ensure you have consistent automatic backups, follow these steps:

Open Anki on your desktop.
Go to Preferences (under the Tools menu).
In the Backups tab, you can adjust the default time between backups. The default setting is 30 minutes.
Specify the number of daily, weekly, and monthly backups you wish to keep. Backup removal starts after two days.

Remember, automatic backups are stored on your local device. If you're using Anki across multiple devices, you should also consider how to sync Anki with AnkiWeb to ensure your data is safely stored in the cloud.

How to Create Manual Backups

While automatic backups are convenient, it's highly recommended to create manual backups, especially before making major changes to your decks or prior to an Anki update. Manual backups can be comprehensive, including your entire collection along with all media files and add-ons, which is not the case with automatic backups.

To create a manual backup:

Locate your Anki folder on your device. This is typically found in your Documents or User Profile folder.
Copy the entire Anki folder to an external drive or cloud storage service. This folder should include the collection.anki2 file and any media associated with your decks.

In Anki 2.1.50+, you also have the option to create an immediate backup via the software itself, which functions similarly to automatic backups:

Open Anki and from the main menu, select File>Create Backup.
Choose a destination on your device and save the backup file.

Remember, to restore from any manual backup, you can use the File>Import option within Anki.

Backing up your data regularly is a critical habit to develop. By combining automatic and manual backups, you ensure that all aspects of your Anki data, including how to add cards to Anki, how to create subdecks, and how to customize card templates, are safely stored and can be restored if needed.

Restoring Your Anki Data

In the event that you need to restore your Anki data, perhaps due to a device change or data corruption, it's important to understand the steps to do so safely and the scenarios where you may lose data. Here's a guide on how to backup and restore Anki data.

Steps to Restore Backups

Restoring your Anki data from a backup is a straightforward process; however, it's important to note that any changes made since the last backup will be lost:

Close Anki if it is open.
Locate your backup file. This will generally have an .anki2 extension.
Copy the backup file to Anki's collection folder, replacing the existing file if prompted.
Re-launch Anki. The application should automatically detect the backup file and restore your data to the state when the backup was created.

For Anki 2.1.50 and later, you can create immediate backups using File > Create Backup. To restore from these backups, simply use File > Import and select your backup file.

If your backup is stored on AnkiWeb, you can force a one-way sync by changing your preferences or, if you're syncing from a new device, choose "Download" to restore your data from AnkiWeb. However, remember that AnkiWeb does not include media files in its backups, so you will need to restore these separately.

Potential Data Loss Scenarios

It's crucial to be aware of situations that may result in data loss:

Restoring from an outdated backup: If the backup you are restoring from is older than the most recent changes you made, you will lose any progress or modifications that occurred after that backup.
One-way sync: Opting to download data from AnkiWeb will overwrite the local data on your device. Ensure that AnkiWeb's data is the most current or that you are willing to lose the local changes.
Corrupted backups: If your backup file itself is corrupted, restoring from it may not be possible. This is why maintaining multiple backups is critical.
Missing media files: As mentioned, media files are not included in AnkiWeb backups. If you rely solely on AnkiWeb for backup, you may lose all media associated with your cards.

It is recommended to close and re-open Anki after restoring your data to ensure the software returns to normal operation and re-enables automatic syncing and backups.

Syncing with AnkiWeb

Syncing with AnkiWeb allows you to access your Anki flashcards across multiple devices, such as your computer and smartphone. To begin, you should sync your Anki with AnkiWeb, which will upload your data to AnkiWeb's servers. This process ensures that any changes made on one device can be updated on all other devices where you use Anki.

For users who need to restore their Anki collection from AnkiWeb, you can perform a one-way sync in the preferences screen, or initiate syncing from a new device and choose "Download" to restore your collection from AnkiWeb. This feature is especially useful if you encounter issues with your local data or switch to a new device.

Limitations of AnkiWeb Backups

While AnkiWeb is a powerful tool for syncing data, it has its limitations, especially regarding backup functionality. Direct backup options are not available on AnkiWeb itself; however, data can be backed up using the desktop and mobile clients, such as Ankidroid and AnkiMobile.

It is important to note that restoration of AnkiWeb collection data will revert your collection to the state it was in at the time of the backup. Any changes or additions made after the backup date will not be preserved during the restoration process. Therefore, regularly exporting your data is crucial to minimize the risk of data loss.

Furthermore, AnkiWeb accounts can be deleted after periods of inactivity, typically around six months. To prevent data loss, it is recommended to export your Anki collection regularly. This export should include your scheduling information and media files. Adopting a 3-2-1 backup strategy—three total copies of your data, with two local (on different devices) and one off-site—is advised for optimal data protection.

Regular exports and backups should be part of your routine to ensure the safety of your Anki data. By doing so, you can continue to use Anki for a variety of learning purposes without the fear of losing your valuable study materials.

Best Practices for Data Protection

When using Anki for your study sessions, ensuring the safety of your data is paramount. By following certain best practices, you can protect your card data, scheduling information, and avoid the heartache of data loss.
