Failed backup to AWS S3

I am running OttoFMS v 4.10.3 on FileMaker Server v20.3.2 on MacOS.

I have setup AWS S3 for remote backup and created a backup schedule via the OttoFMS web console which runs successfully and creates the backups on an external SDD connected to the Mac. However, the files are not uploaded to AWS. Checking the otto-error log I see the following entry

2025-04-29T20:29:02.236Z error Error sending backup to offsite: Error: Command failed with exit code 6: /Applications/OttoFMS/bin/rclone copy --config /Applications/OttoFMS/config/rclone.conf /Volumes/Backups/OttoFMS/offsite/OTTO_OFFSITE_BACKUPS iclinicianbackups:iclinicianbackups/iclinicianapp/dbs -v --use-json-log --include OTTO_OFFSITE_BACKUPS

Any suggestions on what might be causing this? The folder permissions for the OTTO_OFFISTE_BACKUPS folder has the Mac’s administrator account set to Read & Write but no other accounts such as fmsserver or fmsadmin. Could this be the cause?

Hey Neil,

I suspect the permissions could cause a similar problem. Is there a reason you have the permissions set this way? OttoFMS is running as the fmserver user, so if that user does not have permission to access that folder then it would probably error out.

Thanks Kyle. I’ll update the permissions and see if it runs successfully tonight
