Wenn die Festplatte zu klein wird können mit diesem Skript die Aufnahmen z.B. auf ein NAS verschoben werden.

# This script is designed for Vu+ sat receivers with VTI image.
# The idea is to "move" recordings from a local harddisk to a NAS (e.g. Synology DiskStation)
# It is possible make recordings directly to the NAS.
# But in case of no availability or heavy network or NAS load the quality of recordings might be bad.
# So the recordings are always local and will be "moved" to the NAS once per day to free harddisk space.
# The NAS is connected with NFS to the receiver.
# I decided to use the copy command instead of the move command as I recognised data loss (maybe because of protected .ts and .eit files).
# After the copy command I check if the .ts file is existing (the other files are not so important) before I delete the source files.
# Recordings that are marked for deletion are ignored.
