Taking a backup deletes other backups
Running TI 2015 build 6613 on Win10 Home build 10586 backing up to a USB-connected external disk with nearly 2TB free space.
After moving to Win10, I created three new manually-started ‘full’ (i.e. not incremental or differential) backup tasks: to back up one file (task DATABASE in the annexed log), the entire PC (task FULL), and a Documents folder (task DOCUMENTS). Backup was to a new folder on the external disk.
Checking the emailed log after taking the first backup (DATABASE) showed that backup was taken successfully. But before validation, consolidation occurred (why and what with?), and then a previous full+incremental backup IN ANOTHER FOLDER was deleted…!
I then took a FULL backup. This was apparently OK.
Finally I took a DOCUMENTS backup. The backup was taken successfully. But before validation, consolidation occurred (why and what with?), and then the DATABASE and FULL backups WERE DELETED!! And the deletion was confirmed with Win File Explorer.
The deletions are lethal: I could have carried on taking backups not knowing that they subsequently were being deleted.
I only made things apparently work properly by defining three new backup jobs with the each of the three backup tasks using different folders on the external disk.
Could anyone possibly clarify:
- why consolidation need to happen before validation (and what is actually happening as shown in the log)
- why the backup deletions are being made. It is this one which scares me! I only expected automatic deletions when automatic clean-up rules kick in, and then only to the oldest generations of the particular backup task, not backups from other tasks.
