Repo on S3 under AWS Outposts #2659
Description
I'm trying to create a stanza on S3 under AWS Outposts, but I'm getting an UnsupportedOperation error. I have multiple repos, and trying to use S3 on repo2. I'm using the full ARN for the --repo2-s3-bucket option, since S3 on Outpost doesn't use traditional S3 bucket names.
Something like --repo2-s3-bucket=arn:aws:s3-outposts:us-east-1:123456789012:outpost/op-01234567890abcdef/accesspoint/my-pgbackrest-ap
I was able to connect to the bucket with the aws command line client. Digging around, the UnsupportedOperation error from S3 Outposts typically means pgBackRest is trying to use an S3 API operation that Outposts doesn't support. So I am wondering:
- if I missing something
- if there's some incompatibility between backrest and outpost I should be aware of.
This is pgbackrest 2.54.2.
Thanks in advance.
