It is not clear from the article whether this happened because the author upgraded to Snow Leopard, or because they switched their external hard drive to eSATA. If the former, the behavior might be caused by the fact that Snow Leopard is a new operating system, and many of the system files that were in OS 10.5 have changed.
Have any readers that have upgraded to OS X 10.6 experienced the same issue?
- lisper 17y agoIt's both. I upgraded to Snow Leopard, and I remounted external drives. In Leopard, there was an option to warn before deleting old backups. In SL that option has changed to "notify after deleting old backups." That plus deleting the external volumes from the exclude list was the nasty combination.
- Maktab 17y agoFrom what I can tell the behaviour in Leopard and Snow Leopard appears to be identical, it's just that Leopard had a falsely-reassuring label for the option which has now been changed to a more accurate one. Either OS would have deleted your old backups in the same way. The bottom line is that Time Machine is a backup solution with a certain level of archiving as an added feature; it is not a bulletproof archival solution and shouldn't be relied on for that purpose.
- lurch_mojoff 17y agoYou also say that you switched from USB to eSATA. There is a very good chance that from the perspective of the OS these are entirely new dives, maybe even seen as internal drives. There may not be an issue in the Time Machine code, but rather this whole thing is unfortunate edge case of intended behavior.
- lisper 17y agoYes, I think that might be right. That hadn't occurred to me before.
