cut and pasted veeam contents. now I want to copy back

Just creating the names of the folders won't work; veeam will need to use the previous backup to build on the newer one when doing an incremental so you may need to copy the missing files back to your repository.  You could try doing an active full though either way, the database will have those backups referenced and at one point or another will have an issue with those files not being there.  if you try to delete, will throw an error because they are missing.  It's possible it might fix itself when it ages out (depending on your retention settings) but have never had that issue and not sure what would happen.  Best bet is to copy back the pieces of the backup chain were inadvertently moved.

What do I do to make the VEEAM backup work correctly if the copy from the external hard drive back to the original location does not work?  Do I need to create a brand new backup job?

Do I have to copy and paste the entire external drive back to the original location for the nightly backup to work or can I just copy the names of the folders and let VEEAM run tonight?

you have to restore the backup contents to the way they were.


If it fails then you have to do a FULL backup and you will lose your backup history

why don't you use VEEAM to make a copy https://www.veeam.com/blog/backup-copy-job-it-can-do-more-than-just-a-copy.html

So if the restore does not work I would right click the VEEAM job and choose "active full" to do a full backup job?

You said, "as long as the backup chain is complete"

Will this not work because a day will be missing in the chain, or am I not understanding correctly?

that is the only back chain you've got, the missing day there was no backup.

If you put it back, it should just continue and work!

If moving a " repo " - backup location it needs to be done correctly and migrated to carry on as per usual! - as you've discovered.

FYI.  The backup failed.  It said I need to do rescan the repository.
Will this delete any old backups?

Also, after the rescan, if I run the job, will it reduce network performance for users?

possibly.
