Looking to get a NAS backup job to immediately send a copy of backups to S3, customers requirement is 90 days of retention on prem and in S3.
I had initially setup a SOBR with a capacity tier of S3 and enabled "Copy backups to object storage as soon as they are created".
Once this didn't work I came across the doco stating this will not work for NAS backups

Next idea was to create an S3 file gateway and mount this as a share to the Veeam backup server but struggling to find out if this is a supported configuration?
Any other ways around this would appreciated.
Thanks
