Background This article describes how to improve the speed of your SMB share with disabling the policy "Microsoft network server: Digitally sign communications (always) Symptoms creating backups takes unusual long performance of the remote archive volumes are poor (only a few MiB/s) remote share is a Microsoft Windows server no performance problems by using "smbclient" on other Linux clients Explanation Open the "Local Group Policy Editor" on your Windows server and goto "Windows Settings > Security Settings > Local Policies > Security Option". To improve the speed of your share you have to disable the policy "Microsoft network server: Digitally sing communications (always)". After changing the policy you should be able to read and write with normal speed again.     Additional References https://docs.exasol.com/administration/on-premise/manage_storage/create_remote_archive_volume.htm?Highlight=SMB

Background min.io is an S3-compatible storage service (see https://min.io) that can be used as a backup destination (remote archive volume) for on-premise Exasol setups. Unfortunately, as of Exasol 6.2, there remains a minor incompatibility that requires patching the min.io server in order for Exasol to correctly recognize it. The steps below walk you through making your min.io service Exasol-compatible. Prerequisites Have min.io installed in a location that Exasol has access to Ability to reconfigure, recompile, and redeploy min.io Ability to add DNS aliases Have a min.io bucket and access/secret keys setup How to use min.io as an Exasol remote archive volume Enable SSL in min.io and have it listen on port 443 (Exasol will ignore any other port specified) Assuming that your min.io server is minio.yourdomain.com   and it has a bucket named backups, create a DNS alias backups.minio.yourdomain.com which also resolves to the same IP as minio.yourdomain.com In the min.io startup script set the   MINIO_DOMAIN   ENV variable to   minio.yourdomain.com.  This will cause min.io to extract the bucket name from the virtual host passed to it instead of extracting it from the URL path (which is the default) In the min.io startup script set the MINIO_REGION_NAME   ENV variable to   us-east-1 (or other region of your choice). This will cause min.io to include that in all HTTP response headers. Check out the min.io source code from https://github.com/minio/minio.git   and apply the patch below. See the repository's Dockerfile for how to rebuild it:  --- /cmd/api-headers.go +++ /cmd/api-headers.go @@ -51,7 +51,8 @@ func setCommonHeaders(w http.ResponseWriter) { // Set `x-amz-bucket-region` only if region is set on the server // by default minio uses an empty region. if region := globalServerRegion; region != "" { - w.Header().Set(xhttp.AmzBucketRegion, region) + h := strings.ToLower(xhttp.AmzBucketRegion) + w.Header()[h] = append(w.Header()[h], region) } w.Header().Set(xhttp.AcceptRanges, "bytes") Redeploy your min.io server with the patch In the Exasol ExaOperation interface for adding a remote archive volume Set the Archive URL to   https://backups.minio.yourdomain.com Specify the access and secret keys in the username/password fields Specify an Option of   s3   (and any other applicable options) Additional References https://min.io https://github.com/minio https://docs.exasol.com/6.2/administration/aws/manage_storage/create_remote_archive_volume.htm
