I have come to the conclusion that WD Live and TimeMachine just do not get along. I have recommended these to friends and family for a few years, but I suppose no more. I simply can not get it to work reliably. No matter what I do, or how often I keep up with firmware, its the same issue: TimeMachine must create a new backup.
I have 3 Macs backing up to the WD Live via TimeMachine. Two do it wirelessly, one does it over Ethernet. The two wireless are constantly telling me about corrupt sparsebundles, and the need to redo backups…this is about every other week. Now, I get it, these things are all over the house, lids open and closed, so sure, TM gets confused.
But my other Mac, and iMac, doesnt have this problem. Its always connected, and connected over 100Mb Ethernet. But I just got the 6th request to ‘create a new backup’ on this machine alone, in last 6 months. Now, its taking 4 days, literally, to backup 150GB. Mathmatically, it should take about 4 hours to do this, over this speed link. Even if the hard drive were slower than the link, one day should be far more than enough. But 4 days? Something is very, very broken with this product.
I suppose I will have to retire this thing and get a TimeCapsule, as it seems WD just can’t figure this out. I simply can not waste anymore time on this, and can’t recommend these any longer. The fact that WD does not contribute here, and does not seem to even include fixes in the firmware for TM amazes me. (or it doesnt call out fixes in firmware)
