One or more recovery points are not available at therir locations

I guess, depending upon the schedule/frequency of backups, you'll have to run enough backups to create 5 sets of recovery points. Once, this are in place with subsequent backups running, this alert should not generate any more.

Limit is set to 5.  I'm willing to let SSR manage removal of recovery points.  I think I did the manual removal early on.  Given that, how do I get rid of the error alert???

If you ever need to clear up free space on your storage device by removing the recovery points, have a look @ these KB articles for couple of methods:-

Currently, just let your backups run as usual. And what is this setting currently set to "Limit the number of recovery point sets saved for this backup" ?

I bellieve I am "guilty" of having maually removing recovery points.  What can I do to correct this?

Multiple reasons for this alert such as ~

If  the recovery points ever manually removed from the backup destination.

If yes, then one shouldn't be doing it. Best to allow SSR to clean up the recovery points automatically.

If one backup is configured to multiple storage devices which are being swapped

If yes, then a backup job should be setup for each storage destination.

If the desktop system is losing connectivity to the storage destination or if the storage destination is not always connected/online
