excellent point and I agree. This is why all my backups are not created from a single "master". I didn't go into all that, but more specifically, I have 3 working systems (home, office, and weekend cottage). Each of these has a "master". Additions/deletions from these 3 masters are NOT done automatically. I manually add new files, remove duplicates, etc. The only comparisons I do are that when all 3 are manually updated with changes, I can check to see that the (1) total number of files/directories, (2) total number of tracks, and (3) total number of albums are all identical. Then at each of these 3 locations I have backup HDDs that I use freefilesync to keep in sync with the master from that location. At office and weekend cottage I only have one external backup HDD. At home (which I consider the "main" system) I have two USB HDDs containing synched copy of "home" master. The backups are stored not connected to power or a computer. The downside of this is that I have to keep a temporary drive containing files I need to add to all 3 locations and keep a log reminding me what I need to do at each location to keep all up to date. This sounds way more complicated than it is. Just a few lines in a file, with some dates that things happened so I know the status. I suspect that I am not as good about keeping track of minor tagging tweaks across the 3 locations, but I do try. The upside is that I have 3 parallel systems, all with backups, and the files are not cross-contaminating across the 3 sets. Accidental deletion at one location doesn't taint another location. And after adding new files, deleting files, etc. at any location, I always confirm that the totals mentioned above are consistent across the 3 locations. Again, all sounds complex, but really simple and something I just do on a regular basis (I add new rips, etc. (or re-rips in FLAC of old mp3 rips) about every week or two; I don't add files each time I rip a new CD and instead wait until I get a week or two's worth and then do all the updating. *Home:* VortexBox 4TB (2.3) > LMS 7.8 > Transporter, Touch, Boom, Radio (all ethernet) *Cottage:* VBA 3TB (2.3) > LMS 7.8 > Touch > Benchmark DAC I, Boom, Radio w/Battery (all ethernet except Radio) *Office:* Win8(64) > LMS 7.9 > Squeezelite *Spares:* Transporter, Touch(3), Radio(3), Boom, SB3, CONTROLLER *Controllers:* iPhone6 & iPadAir2 (iPeng8 & Squeezepad), CONTROLLER, or SqueezePlay 7.8 on Win7(64) laptop *Files:* ripping: dbpoweramp > FLAC; post-rip: mp3tag, PerfectTunes; Streaming: Spotify ------------------------------------------------------------------------ garym's Profile: http://forums.slimdevices.com/member.php?userid=17325 View this thread: http://forums.slimdevices.com/showthread.php?t=106109 _______________________________________________ discuss mailing list discuss@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/discuss
