OpsCenter 5.2.1 Release Notes

Release notes for the OpsCenter version 5.2.1 release.

Backup Service

  • Fixed issue causing restore to fail for thrift tables backed up with OpsCenter 5.1. (OPSC-6156)
  • Fixed issue causing restore to fail for S3 backups created in OpsCenter 5.1 outside of us-west-1. (OPSC-6079)
  • Dramatically improved upload speeds to S3. Download speeds during restore have been improved some, but will be improved further in future releases. (OPSC-5067)
  • Fixed issues with backups to S3 falsely appearing to be stalled in some edge cases; this is a logical bug found in code that has never been reported in the wild. (OPSC-5935)
