How Long Does CSBS Take to Back Up and Restore an ECS?¶
The initial backup for an ECS is a full backup and subsequent backup operations are all incremental backups. Therefore, the initial backup takes a long time and subsequent incremental operations take shorter times. For example, a full backup of a 100 GB ECS takes approximately 30 minutes, and an incremental backup of 15 GB takes approximately 6 minutes.
After the instant restoration function is enabled for CSBS, it takes about several minutes to restore 100 GB data.
