  • 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.
  • Directories can be added or deleted in replication mode. This feature is available only to the users in the whitelist.
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 statuses of download and upload 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.
  • The replication mode of file gateways is enhanced to automatically replicate data to on-premises clients. This feature is available only to the users in the whitelist.
Optimization of user experience:
  • CSG supports API operations.
  • CSG can be integrated with Cloud Monitor.
  • The upload performance of big files in file gateways is improved.
  • Paying for network bandwidth upgrades is supported.
Newly supported regions:
  • Malaysia (Kuala Lumpur)
  • US (Silicon Valley)
  • US (Virginia)
v1.2.0 January 8, 2020 New features:
  • Disk encryption based on a bring-your-own-key (BYOK) solution is supported for file gateways of the Enhanced and Advanced types. This feature is available only to the users in the whitelist.
  • 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 for uploading 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 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 and multiple users to read data from the same gateway at the same time.
  • Windows access-based enumeration (ABE) is supported for file gateways. This feature can be used together with the Active Directory (AD) service to separate 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)
