Removing backups older than X number of days

[rondog]

I remote backup my DVR to an FTP. Is there a way to tell it to delete files older than X amount of days? I can create a PHP script that will do this for me, but wondering if it's built into the amcrest software. I have this:

I know this thing backups locally, but what is to say an intruder takes the DVR?

Hello rondog,

Unfortunately the Amcrest software has no option to auto delete files on external sources like FTP.
