Hi Ronni Thanks for clarification of backups.backupdb within the sparsebundle. In the past I’ve only used “Show package contents” to view the sparsebundle.
After double clicking I get a warning - “The following disk images couldn’t be opened (-image-) resource temporarily unavailable.” It’s not important to follow this issue at this time, I’ll check it later. I would be good to view the backupdb as I assume it will show real dates, rather than “bands”. Entering Time Machine itself to see what dates are available is not very convenient. The backup range shown on TM > Preferences is very inaccurate and misleading.
