I am continuing on working on the backup and restore tools project Android Backup and Restore Tools
A few days ago people asked wether the project supports work profiles, too. I was not sure so I investigated what needed to be done to support work profiles. It turned out that supporting them was more easy than I was expecting at the beginning. Principally It was sufficent to add a user parameter to identify the "partition" which should be used for backup / restore. The rew release can be downloaded directly from Github
