Trying to delete old backups to make room.
How can I tell which backups are *full* backups? (please continue reading to see why the obvious answer doesn't work)
Under Backup and Restore > Manage disk space > View Backups, I select *oldest* Backup Period (there are 4), hit Delete, get a cautionary message:
"Are you sure you want to delete the most recent file backup?"
If I select any of the more recent Backup Periods, I only get a standard confirmation request (i.e., without "the most recent")
I don't want to delete the last full backup until I've made a new one.
"Create new, full backup" is NOT in the left pane options list in the Backup and Restore window.
The past several regularly scheduled backups have failed ("was cancelled"), I suspect due to lack of space. (Backing up to a networked RAID array, avail space only 1TB, backup size approx 1 TB)
3 of the 4 Backup Periods are sizeable, but as I've downloaded lots GBs of image files in this time, I can't tell if the oldest Backup Period is the only one with a full backup or not.
