Warning messages with Time Machine


I’ve been using my 1tb My Book World Edition (latest official firmware loaded) with Time Machine for my backup.

The backups are completing successfully, however when I check the logs I notice the following warning messages:

“Warning: Destination /Volumes/WD_Backup does not support TM Lock Stealing”

“Warning: Destination /Volumes/WD_Backup does not support Server Reply Cache”

What do they mean, should I be concerned?



I’ve noticed that as well on my 2TB, and although I don’t have the answer, I to would like to know what they mean.  That being said, TM does appear to be working as it should.  Much better than the Seagate GoFlex drive I initially purchased (and returned).
