Back last month, there were reports that TWRP, the open-source recovery project was preparing to allow full Nandroid backups directly to PC. Now, TWRP v3.1.0 comes with full support for Nandroid backups directly to PC among many other new features.
The full Nandroid backup directly to PC means that whenever a user is connected to PC and takes a TWRP Nandroid backup then the backup gets directly backed up to the PC without storing any portion of the data on the phone. This feature comes in very handy when the user wants to take a backup before flashing any new rom but doesn’t have storage capacity to do the backup on the phone. TWRP v3.1.0 also comes with more features other than Nandroid backup to PCs like support for alpha/beta OTA update zips in the recovery. This feature is only available for Pixel and the Pixel XL phones which are the only phones to have A/B partition for faster updates.
The TWRP v3.1.0 also fixes a bug with the direct boot feature where whenever a user tried to backup/restore any particular application then all the data from the application gets wiped. The other notable change in this update is that the TWRP v3.1.0 will now prompt users to install the official TWRP app from the Play Store. The official TWRP app is very useful to keep the TWRP version up-to-date with features like directly flashing recovery from the app among many others.
