Intro:

I have been looking for a way to backup my android phone regularly and easily. For security reasons I dont want to enable android developer options like usb debugging. My backup strategy is to store the data locally on my hard drive and then pack and encrypt the files and uploading them into my cloud.

Link to the awesome adbackup script by BojanStipic

Example

You have to create the same folder structure like your phone generates by connecting in MTP mode.

fnz@os:/run/user/1000/gvfs/mtp:host=ANDROID_PHONE$ tree -L 2
├── Card
│   ├── Alarms
│   ├── Android
│   ├── DCIM
│   ├── Documents
│   ├── Download
│   ├── Memes
│   ├── Movies
│   ├── Music
│   ├── Notifications
│   ├── Podcasts
│   ├── Ringtones
│   ├── Sync
└── Phone
   ├── DCIM
    ├── Documents
    ├── Download
    ├── Pictures
    ├── Podcasts
    ├── Ringtones

filesystem example with selected folders for backup

fnz@pop-os:/media/fnz/Volume/backup/phone$ tree 
.
├── Card
│   ├── DCIM
└── Phone
    └── DCIM

now just launch the script with the given path to your backup folder adbackup /media/fnz/Volume/backup/phone

output should look like this:

fnz@pop-os:~/code/sh/adbackup$ adbackup /media/fnz/Volume/backup/phone
Device:


Backup root directory:
/media/fnz/Volume/backup/phone

Leaf directories found: 
sed: -e expression #1, char 11: unknown option to `s'

...

CONCLUSION

the script will create incremental backups when run repeatedly. It is suitable for those who do not want to share developer / usb debugging permissions for their android smartphone. in case of theft and the possibility of future android debugging exploits, it is for me a reliable and secure way to backup my android phone.
