Hi all, After the scare of a damaged iTunes library file causing me to lose all my playlists, playcounts, podcasts etc and other metadata last night I had to revert to a (thankfully) fairly recent backup that I made of my iTunes folder in order to rebuild my library. All my music is stored on a partition of my vista laptops internal hard drive, and the iTunes library folder is in the standard My documents/music location on the C drive. I do not consolidate my library as I like to maintain the folders myself. I back up both the music files and iTunes folder regularly to an external USB hard drive which takes a few hours as it is a large library. I would like to know if there is any software out there that can recognise when a file has been updated/altered and back it up at set intervals (say every other night). Obviously I could manually do this but it would be easier if there was a program out there that I can tell to back up my iTunes folder and the contents of my music partition, and for any future back ups to only copy the files that have been altered since the last back up (for example if I decide a particular albums genre needs changing, I would then want to back up to reflect the change in this albums ID3 tags, and the updated library.xml file but not to take up time re-copying the entire TV shows folder which hasnt been changed since the last back up, for example). I know its a long winded question, and I hope someone was able to understand what Im getting at!
