Description
Running cbbackupmgr info against an S3 backup archive returns an error. The problem is not seen when run against a file system archive.
Note: The example below is for an S3 backup using the EC2 instance profile for the S3 bucket access – this does not affect the problem, as I see the same error when the cbbackupmgr info command is run against an S3 backup archive that was created using the Backup Service UI with S3 hmac credentials.
Error:
$ cbbackupmgr info -a s3://my-test-bucket/ec2_backups --obj-staging-dir /home/ec2-user/couchbase_staging
|
|
|
Error getting archive information: failed to get repository metadata: unexpected error while fetching objects: unexpected error from download pool: failed to open file at '/home/ec2-user/couchbase_staging/ec2_backups': open /home/ec2-user/couchbase_staging/ec2_backups: is a directory
