.
Otherwise, it'll display an error:
C:\Users\User\AppData\Local\Android\Sdk\platform-tools>adb shell bu help
error: no devices/emulators found
When you've connected device, run adb shell bu help
- it will output something similar:
C:\Users\User\AppData\Local\Android\Sdk\platform-tools>adb shell bu help
backup [-f FILE] [-apk|-noapk] [-obb|-noobb] [-shared|-noshared] [-all]
[-system|-nosystem] [-keyvalue|-nokeyvalue] [PACKAGE...]
write an archive of the device's data to FILE [default=backup.adb]
package list optional if -all/-shared are supplied
-apk/-noapk: do/don't back up .apk files (default -noapk)
-obb/-noobb: do/don't back up .obb files (default -noobb)
-shared|-noshared: do/don't back up shared storage (default -noshared)
-all: back up all installed applications
-system|-nosystem: include system apps in -all (default -system)
-keyvalue|-nokeyvalue: include apps that perform key/value backups.
(default -nokeyvalue)

adb shell bu help
does nothing for me, even after I connect a device. I can adb shell
into the device, but bu help
just sits for a second or two, then returns with no output. bu
alone waits for a second, then says "reset_reason_init" "Killed"
