Playlists (Backup discussion)

^^
LOL, too easy, I should have known!! Thx.

I have one question Mike.
When you run this script does it overwrite your previous backup? If so, what happens if auto update deletes missing files? Your backup will now reflect the changes.
What I was hoping for is the ability to date stamp the backups. Could that be added to the script?

To protect the integrity of your playlists from auto update and events outside of MC you need to manually back up your playlists by exporting them. I think the M3U format is the most likely choice.

If you turn off "Fix Broken Links", then MC seems to protect playlist integrity. Which is not to say that you shouldn't export your playlists, but here was my experiment with Auto-Update + Fix Broken Links.
I left Auto-Update on and went into a folder that was managed by MC and copies one of the audio tracks in Explorer. It showed up as expected in Media Center. I dragged that file into a playlist, and then deleted it from Explorer. The icon then changed to show that the file was gone, but the playlist didn't update. Then I could remove the file from the library at my leisure.
The one type of problem not addressed by this is the database nature of MC vs. the snapshot nature of M3U. A playlist in MC is just a list of objects in the database. As the database changes over time, the playlist will automatically update to account for tag changes, edits to the file, etc. An M3U is static and records things as they are at the time you export. There's utility in both ways, certainly.

If you're referring to the MC Export of all Playlists, the answer is Yes, it overwrites the existing files from the previous export. But the order of events is: 1. Export 2. Backup files, so the next export does not affect the previous backup
If you're referring to my backup script, the answer is No. I have a rotating device/folder increment that allows me to control the number of backup "versions" I keep.

THis is an excellent point and since we know this, appropriate actions can be taken.

I have a very simple view of a playlist. It is nothing more than a sequental list of songs to be played. An M3U format does that just fine. When things are updated in the rest of the file and let's say I import a M3U backup into MC then all the updates will be there.
As I said at the begining of the post, my interest leans toward the audiophile. With that in mind, what I would like to be able to do with a playlist is to adjust gain, work through several different kinds of mixing and be able to store that in the playlist file. You hit on some of those issues in your DJ thread.

Thanks, that will work for me. I can set up a folder for each month and export to the current month.
