TWRP Argument list too long

[JimyKK]

I receive the following error when backing up the Data partition via adb shell:

Backing up /data... /system/bin/onandroid[1876]: busybox: Argument list too long

The backups had been working just recently and I can't think of any changes to the system I have done. I am running the Xposed framework but disabling that doesn't fix the issue. If I backup using -o instead of -w I encounter no errors.

This is a busybox issue, Try using a different busybox.

OK sorry about that. Any recommendations for which busy box to use? I have used the installers on the play store: BusyBox by Stephen (Stericson), BusyBox Installer by JRummy Apps Inc, BusyBox X by Robert NEDIYAKALAPARAMBIL and Busybox On Rails by Team Trickster. They all kick up the same error

As far as I can tell they are installing the latest version of busy box
