Partitions Backup Restore is a free Android app developed by Wanam under the category of Business & Productivity. It allows users to create a backup of their device partitions, including sensitive partitions like Bootloader, Kernel (Boot), EFS (IMEI), and Modem partitions. This backup can be saved on the device's SD card or external SD card. The app supports three backup formats: raw partition image, tar archived image, and compressed GZ image. Partitions restoration is also supported but recommended only for small partitions. The app supports both stock and custom ROMs and requires root access. However, the restoration feature should not be used for testing purposes, and EFS/Modem backups should not be left on the SD card.

The app also highlights all related IMEI/EFS partitions and partially supports Mediatek devices. However, some partitions may not be displayed due to the lack of a specific block number for device mapping. All backups are saved on the device's SD card in the PartitionsBackups folder. Overall, Partitions Backup Restore is a useful app for Android users who want to back up their device partitions and keep their data safe.
