Retention - number of backups = 1 really means what?
How do I interpret this?
If Weekly (Sat) full, Daily incremental (M-F) and number of backups = 1
Does that mean it only keeps 1 full and 1 incremental around? Or does it recognize the plan and keep a complete set - 1 full 5 incrementals.
Either way, when does it delete the old ones? Is it smart enough yet to know that after my full on Saturday that it can delete the prior Full+Incrementals?

Dear Raphael, what exactly do you mean when you say "but remains in a single file with only the latest backup (full or incremental, whatever was started before)". Does this mean that I only have the latest backup (i.e. Monday and Tuesday on a Tuesday?), or do I always have the last full backup included?
Thanks for clarifying

Hi Mario,
you will have always a full backup depending on the latest backup you had taken.
So when you take a full backup it is the only backup in that archive.
When you take an additional incremental backup it will merge the existing full backup and the new incremental backup, in result you will have only one backup in the archive (including the latest incremental changes).
When you take a new full backup is will replace the archive contents, in result there will be the newly created backup in the archive.
Hope it is some more understandable.
