Hello,
BESR in most cases handles this by means of the "limit number of recovery points saved for this backup" feature. If I set the number for this feature to "1", then BESR 7.0 will do the following:
1. Create the first backup when the job runs for the first time
2. Create the next backup when the job runs for the second time, and after successful completion of backup, delete previous backup (created in step 1).
Each time the backup runs thereafter, when the backu completes successfull the previous backup will be deleted. So enough space for two backups needs to exist at the backup destination, but only one backup is kept.
Let me know if that makes sense.
You could alternatively have a batch file run as the part of the backup job that goes out to the backup destniation and deletes all backup files (*.v2i, *.iv2i, and *.sv2i) if that was preferable.
I've never tried that myself.
Thanks.
