On initial setup, the app prompts to select the desired locations for the backups. The locations currently supported are Google Drive, Dropbox, OneDrive and local storage on the phone.
If the local storage option is selected, the files are stored, by default, in the “SMSBackupRestore” folder of the primary storage area on the phone. On most phones this is the folder path “/storage/emulated/0/SMSBackupRestore/” but it can vary based on how the phone was set up. There is an option under Menu > Settings > Backup Settings > Local backup folder to change this folder. The same screen allows selection of custom folder anywhere on the phone or external SD Card (if available).
If only cloud locations are selected then the app stores a local copy of the backups in the app’s internal storage folder (usually “/data/user/0/com.riteshsahu.SMSBackupRestore/files”) before uploading to the cloud account. Once the backup is successfully uploaded to the cloud account, this local copy is deleted.
