On the Huawei Ideos S7, rebooting into recovery with a stock recovery partition will result in the wipe of all userdata (data, cache).
This includes the ordinary methods of entering recovery, via:
'reboot recovery' from shell on the device itself
adb reboot recovery
or the Menu+Send+Power combination
Any of these actions will overwrite the misc partition and flag the bootloader to boot directly to the recovery image with the wipe boot parameter.
You need to flash a 'properly' modified recovery image if you do not want to risk losing user data. In addition, you need to save a backup of your misc partition to restore, so you can return to normal bootloader operation by restoring your misc partition backup.
