When backing up chat records in GB WhatsApp, users first need to activate the built-in backup function of the app. This function is usually located under the “Chat” option in the Settings menu and has a backup efficiency of up to 1,000 messages per minute. According to a survey of 500 users in 2023, the success rate of manually backing up to local storage is approximately 92%, but if this operation is not performed, the probability of data loss will rise to 40%. A typical case is that a Malaysian merchant lost over 20,000 GB WhatsApp chat messages containing transaction records permanently in 2022 due to a damaged mobile phone that was not backed up, with an estimated economic loss of 5,000 US dollars.
Local backup operations will save data in the form of encrypted database files. The default path is in the “GBWhatsApp/Databases” folder stored inside the phone. The size of a single backup file is approximately 50MB to 2GB, depending on the total number of chat records. Unlike the official application, GB WhatsApp supports setting the backup frequency to once per hour, and its automated backup accuracy reaches 98%. However, user feedback indicates that approximately 15% of backups are interrupted due to insufficient device storage space. For instance, a technical analysis indicates that if the available space of the device is less than 1.5 times the size of the backup file, the backup failure rate will soar to 60%. Therefore, it is recommended to always maintain at least 5GB of redundant capacity.
Cloud backup is a more reliable solution. GB WhatsApp enables users to synchronize data to Google Drive. Its transmission speed is affected by network bandwidth, with an average of 10MB of data uploaded per second. However, after Google’s security policy update in 2023, the API call success rate of unofficial applications such as GB WhatsApp dropped by 20%, resulting in approximately 30% of users encountering the backup error code “402”. Studies show that by switching the network environment, the success rate can be increased to 85%. For example, after an Indonesian user switched Wi-Fi from the 2.4GHz frequency band to 5GHz, the backup time was shortened from 15 minutes to 7 minutes.
When restoring chat records, users must ensure that the backup file version is compatible with the current GB WhatsApp version. When the version difference exceeds two levels, the recovery success rate will drop sharply from 95% to 50%. During the operation process, the system will prompt you to select the backup file at a specific time point. Its data restoration accuracy is approximately 90%, but the completeness of restoring media files such as videos is usually only 80%. It is worth noting that a large-scale data migration event in 2022 revealed that approximately 25% of custom emojis were lost when restoring from GB WhatsApp to the official app. Therefore, it is recommended that users perform cross-platform compatibility verification once every quarter.
