I've done a first test with a 6.95 GB folder. First backup of all the files, then I changed ONE tag on all the test files (with foobar), and I did a new backup. Here are the results of the second backup :sent 12.20M bytes received 14.46M bytes 23.52K bytes/sectotal size is 6.95G speedup is 260.51... so, considering the small amount of sent/received data, I think it really works ! What do you think ?
So you are right, all my tags are very stable now.The thing is that very recently, I have felt the need to add a new tag field to ALL my music library. FYI it's the Dynamic Range tag, automatically generated by the foobar component.This sort of thing happens once in a while. You just need to add a new tag to all your music, even if for all the other tags it has become a very static entity, that's all.
washu, I hear you. However, I don't agree with you. I prefer reading 800 GB and writing a very small % of it, rather than writing 800 GB. I don't see why there should be more load on the drives. Writing is more stressful than just reading.
If you have a real PC running debian then that does change things a bit. Most of the time when I hear "NAS" I assume a consumer grade limited device.
It's been a while since I've setup rsync on debian, (I'm more into BSDs), but I'll see what I can find. A quick Google shows several tutorials so that should at least get you going. I don't mind trying to help out, if you run into some specific problems I'll try to help out.
This doesn't change my caution about drive wear. The I/O load will be the same or greater. If you are concerned about that then you should look at upgrading your network to gig-e for faster transfers and just use a normal sync program.
Set up an rsync daemon on the NAS box. I used this tutorial.Then from the Windows machine you run something like:rsync -avh /Localdirectory/ wcs13@NAS::NAS/Remotedirectory
