adbackup 1.0.0

Backs up photos and videos from an Android phone over adb - copies only what's missing and keeps the real capture dates.

ADBackup

Actually a good way to back up photos and videos from an Android phone to your PC over ADB, keeping the real capture date on each file.

Why

It always annoyed me that there's no proper way to sync photos and videos off a phone with adb. adb pull makes you download everything again, adb sync throws away the picture capture dates, and either way you're typing out commands by hand every time. So I made this: point it at a folder, pick what you want, and it copies only what's missing and fixes the dates afterwards.

Your phone is only ever read from - ADBackup never deletes, moves, or renames anything on it.

Using it

1. cd into the folder where you want the files saved.
2. Plug in your phone with USB debugging on.
3. Run adbackup.

It finds the phone (approve the debugging prompt if it asks), then shows a little folder browser, DCIM is at the top, folders above files. Move with the arrow keys, Enter to open a folder, Backspace to go up, S to pick the folder you're in, Q to quit.

Then it asks a few things (arrows + Enter): include subfolders, update or redownload everything, correct the dates, and how many files to copy at once (just press Enter for 4). It shows how many are new vs already backed up, you confirm, and it copies them with a progress bar and stamps each file's Created/Modified date to when the photo or video was actually taken.

The folder you picked is recreated by name in your destination, e.g. picking /storage/emulated/0/DCIM/Camera gives you a Camera\ folder.

Installing

You need ADB on your PATH (Android platform-tools - check with adb version) and USB debugging enabled on the phone. Then:

py -m pip install --user pipx
py -m pipx ensurepath      # then open a new terminal
pipx install adbackup

pipx ensurepath puts the adbackup command on your PATH, so after that it just works from any folder.

Latest from source instead: pipx install git+https://github.com/EmilHaase/adbackup.git

Speed

Files are pulled in batches of up to 100 per adb process instead of one command per file, so transfer time isn't eaten by process startup. Every file is still size-verified and retried individually if needed. Live speed and ETA are shown in the progress bar.

I recommend using a good USB 3 cable - with one I usually get about 250 MB/s. Of course lots of smaller files download slower than a small amount of big ones, since each file has a fixed per-file cost.

Disclaimer

I have to apologise for a limitation I could not work around: photos and videos taken before January 1, 1601 cannot be dated correctly. Windows file timestamps simply do not go back any further, and there is nothing I can do about it. Files with a capture date before 1601 are treated as having no readable date - if you picked the option to move such files, they will be sorted into the _ADBackup_errors folder and you will unfortunately have to date them manually. I am genuinely sorry to everyone affected by this.

Notes

• Dates come from EXIF for images (JPEG, HEIC, RAW, …) and the container creation time for videos. If a file has no readable date you choose up front what happens - keep it with the file's own date, move it to an _ADBackup_errors folder, or skip it. Nothing is ever removed from the phone.
• Anything skipped or failed is listed at the end and written to _ADBackup_report.txt in the destination.
• Re-running is safe: in update mode it skips whatever's already there.
• Edge cases are handled: filenames Windows doesn't allow are renamed safely (and still recognized on re-runs), and paths longer than Windows' 260-char limit work fine.
