Learn something new everyday - today it was there is a file backup command. I also sync my directory to one on my home server so I can share files between my desktop, laptop, and my wife's computer.
File, Backup has been around since august. Here is the readme notes
3.1.0: Aug 7,2013 - Enhancement: (frankr) new single BACKUP option now.
Goto to "File,Backup" and every xml file you have will be created in the new Backup sub-directory under show show directory.
How big are xLight sequences? The xseq file for 12K channels is around 30mbytes, the xml of your sequence is around 30kbytes. As comparison the XML file for LOR for the same song is 800mbytes, for LSP 1.2gbytes. Because xlight sequence files are so small (normally < 50kbytes), we can back them all up quickly.
How long to back up over 100 sequences? < 1 second.
How much space does 100 sequences take? < 10 mbytes
How many times can you do this per day? 1000's.
How to use this feature? Just do a "File, Backup" before getting new versions.
I would do a copy if you plan on doing lots of edits. Basically get yourself protected.
i would use it lots, especially if you are actively changing things around.
