  • The number of active messages in a synchronization group can be displayed.
  • Replication mode is globally supported in CSG.
Replicate data

  • Renamed files can pass the cyclic redundancy check (CRC).
  • The performance of data duplication in replication mode is improved.
  • The stability of NFS access to file gateways is enhanced.
  • The load time of large file sharing systems is shortened.
Newly supported region: China (Heyuan)
v1.4.0 April 10, 2020 New features:
  • Data can be duplicated by using file gateways in replication mode. This feature is available only to the users in the whitelist.
  • Replication mode can be enabled or disabled. This feature is available only to the users in the whitelist.
  • Replication mode allows you to add and delete directories. This feature is available only to selected users.
Optimization of user experience:
  • Express synchronization across regions is supported.
  • The description for the UTF-8 verification of the file names is included in the instructions for file gateways.
  • The status of downloading and uploading queues can be displayed for file gateways.
  • The passwords of on-premises gateways can be reset.
  • Log data can be collected by Log Service by using on-premises gateways.
Newly supported region: Japan (Tokyo)
v1.3.0 March 6, 2020 New features:
  • The transfer acceleration feature is supported by file gateways.
  • Replication mode of file gateways is enhanced to replicate data to local clients. This feature is available only to selected users.
Optimization of user experience:
  • API operations can be called in CSG.
  • CSG can be integrated with CloudMonitor.
  • The upload performance of big files in file gateways is improved.
  • Paid network bandwidth upgrades are supported.
Newly supported regions:
  • Malaysia (Kuala Lumpur)
  • US (Silicon Valley)
  • US (Virginia)
v1.2.0 January 8, 2020 New features:
  • Disk encryption by using bring-your-own-key (BYOK) is supported for file gateways of the Enhanced and Advanced types. This feature is available only for the users in the whitelist.
  • Enhanced and advanced file gateways allow you to associate multiple OSS buckets with the same share.
Associate a share with multiple OSS buckets
Optimization of user experience:
  • Fragment optimization based on the Network File System version 4 (NFSv4) protocol is supported for file gateways. If multiple requests to upload a file to the OSS bucket are sent, only one of the requests is processed. File gateways cannot mount shares on on-premises clients over NFSv3.
  • The express synchronization feature is optimized on the NFS client side. Metadata updates can be discovered by NFS clients in real time.
v1.1.0 December 26, 2019 New features:
  • Express synchronization is supported for file gateways. This feature detects data changes in OSS buckets without the need for a full scan. Express synchronization allows a single user to write data to a gateway and multiple users to read data from the gateway at the same time.
  • File gateways support Windows access-based enumeration (ABE). You can use this feature together with the Active Directory (AD) service to isolate access requests from different accounts.
Optimization of user experience:
  • The specifications of CSG can be upgraded.
  • Automatic renewal of subscriptions is supported.
Newly supported regions:
  • China (Chengdu)
  • Indonesia (Jakarta)
