Offline forms help you collect the data you need to register new users, understand customer satisfaction, process orders, etc., in low-connectivity areas. However, offline forms are not without their flaws, they come with a major vulnerability: the risk of data corruption or loss due to device failures, sync errors, or accidental deletions.

Losing data is one of the most painful things that can happen to you as a business owner, but there’s hope— you can recover the data (in most cases). Let’s talk about the most common ways to recover offline form data after they have been lost or corrupted.

Understanding Offline Form Data Loss & Corruption

An offline form allows you to collect respondents’ data through digital forms without an active internet connection. The form stores submissions on the device (phone, tablet, or laptop) temporarily and syncs to the cloud once the connectivity is back. 

Using offline forms ensures uninterrupted data collection, but they also introduce some risks, since the data isn’t immediately backed up to the cloud. For example, you’re a census data collector in a remote area, and before you get to an area with good connectivity, you misplace the device you collected the census data with. This means the data you collected isn’t in your server yet, so you can’t retrieve it from the cloud— bottom line, it’s lost. You’d have to go back to the location again to collect the data afresh.

Common Causes of Offline Form Data Loss & Corruption

The following are the most common causes of losing offline data:

1. Device Failures: if your device or the respondent’s device crashes, it falls and there’s irreparable hardware damage, or it gets stolen and the thief wipes the data, the data saved on the local storage is gone. Also, if your phone, laptop, or tablet’s battery dies mid-collection, some data may be lost because local storage isn’t instantaneous like online storage.
2. Sync Errors: If your upload is interrupted when reconnecting to the internet, the data could get corrupted. Also, if there is a conflict merging offline and online data, the data gets corrupted or lost.
3. Software Glitches: Although rare, if your form app crashes or the browser you used to access the form crashes, it could corrupt the stored submissions. Sometimes, buggy updates could also wipe the device’s local database.
4. Human Error: Improperly closing the form application or abruptly powering off the device could lead to data loss. Also, if a customer with a bad network gets tired of the website’s slow loading, they could clear browser history and data, hoping it would help the connection, hence, deleting the saved data. 

Why Offline Form Data Loss Is a Big Deal

Generally, losing data is a big deal, but the severity of the damage depends on your industry or use case. Here are some of the most affected industries:

• Field Researchers: losing data as a field researcher means wasted time, effort, and money. Imagine weeks of environmental or social research collecting views about different topics from people.  Trying to get diverse perspectives, and it’s gone in seconds. Even if you’re able to meet the people again, there’s no guarantee they will recollect things the same way, or you won’t introduce repetition bias because they have answered the questions already. 

• Sales & Customer Service Reps: Missing Leads: If you are unable to sync contact details from offline events like trade shows or door-to-door sales, you can’t follow up due to corrupted CRM entries. 

• For Healthcare & NGO Workers: This is one of the most severe cases because you’re dealing with human lives. If you lose patient medical records before reaching clinics, this means you can’t develop a treatment for them. If a patient is in severe pain or needs urgent care, this delays the process and their journey to being healthy.  For NGOs, losing offline data could mean losing beneficiary details for disaster relief.  

• Event Organizers: If the scanned tickets or waivers don’t sync after the event, you have no list of attendees, and you can engage or nurture them as leads. You also can’t get feedback about your event, so you’d have to guess your improvement areas.

First Steps to Take If Your Offline Form Data Is Lost or Corrupted

If you discover that you can’t access data from your offline data collection, don’t panic. Here’s what you can do:

1. Stop Using the Device Immediately- You may overwrite the recoverable data if you continue using the device for data collection. The next step is to disable auto-sync to prevent overwriting existing files.
2. Check for Temporary or Backup Files: Search device storage for partial/incomplete form submissions; it should be saved as a .tmp file. You can also check the storage for the auto-save version.
3. Try Data Recovery Software: You can also try using data recovery tools like Recuva (Windows), Disk Drill (Mac), or Dumpster (Android). Keep in mind that you have to disable auto-sync immediately for this to work; these tools work best if you attempt the recovery before new data is written to storage.
4. Contact Your Form Provider’s Support: Some offline form apps keep hidden backups, and they can access their recovery logs.
5. Check Cloud Sync History: If the data was partially synced, you might be able to recover some submissions. Check the version history in your cloud storage, e.g., Google Drive or OneDrive.
6. Attempt Manual Reconstruction: This is the last resort if all else fails. Start by cross-referencing field notes or paper backups, sms or email receipts, audio recordings, or photos if any were taken of the completed forms or interviews.

How to Prevent Future Offline Form Data Loss

While the recovery steps mentioned above can help you recover lost data, they don’t always work. Sometimes, you lose the data permanently. Here’s how to ensure you never lose them in the first place:

1. Enable Automatic Local Backups: Configure your form app to save duplicate copies with a backup frequency. For example, you can set your backup frequency to saving a copy of the local database at regular intervals e.g., every 5 minutes. 
2. Implement Two-Way Sync Verification: Use form creation apps that provide sync confirmation receipts. For example, your sync confirmation receipt could be “5 forms successfully synced at 7:45 AM.” This helps you know the precise time your data stopped syncing and helps you trace the data you need if data gets lost. So, if you’re collecting beneficiary information for your NGO, you know the exact people to meet to recover the information you lost. 
3. Adopt Reliable Offline Form Platforms: When choosing an offline form builder, make sure you choose a platform that enables end-to-end encryption during sync. The platform should also have version control for submissions and built-in recovery modes.
4. Configure Smart Storage Rules: Set up automatic cloud backups when the connection is available so the data gets safely stored in the cloud as soon as possible. You can also store data on removable SD cards (not just device memory) as a backup for your backup.

Operational Best Practices

1. Establish Field Data Protocols: Create backups for your backups with the triple save method- primary device storage, removable media (SD cards or hard disk), paper backup for critical fields.
2. Train Staff on Data Safety: Create a mandatory  “sync check” before data collection personnel can leave the collection sites. You should also teach them manual export procedures for emergency backups.
3. Schedule Regular Data Audits: Create a periodic verification of sync completeness. This will help you spot any discrepancy between the collected data and the uploaded data.
4. Maintain Equipment Properly: Some of the most common causes for data loss and corruption are device damage and low battery mid-collection, so carry portable chargers to prevent battery failure and use rugged cases to protect your device in case it falls.

Advanced Protection Measures

1. Implement Blockchain Verification: Using blockchain for data storage ensures that once data is submitted, it can’t be rewritten. This way, your data can’t be corrupted.
2. Use Hybrid Paper-Digital Systems: You can create QR-code-linked paper forms as a failsafe, so you can still have the physical form if the digital data is lost.
3. Deploy Local Network Sync Hubs: Use portable WiFi hotspots that cache submissions. You can also enable peer-to-peer syncing in remote areas. However, keep in mind that this would require additional security measures. This is because you increase your attack surface with these extra setups.
