Full backup of VMware virtualization platform
Fully back up the VMware virtualization platform selected by the user to the designated UCACHE disaster recovery cloud. Each time it backs up, it will back up valid disk data to the UCACHE disaster recovery cloud according to the type of virtual machine disk, and generate a time point for recording the contents of the backup. For example, thick provisioning zero-thick disks (Thick) back up the same amount of data as the entire disk, while thick provisioning delayed zero-thick disks and thin provisioning disks (Thin) only back up the amount of data occupied by the disk space when CBT takes effect.
Incremental backup of VMware virtualization platform
Based on the last backup of the user virtualization platform, after the virtual machine disk change block information is obtained by VMware CBT, the virtual machine disk change data block is backed up to the UCACHE disaster recovery cloud, and the corresponding time point is generated at the same time. .
VMware virtualization platform data recovery
VMware virtual machines can be restored to the original virtualization platform or other virtualization platforms by browsing data recovery through the web management console in the UCACHE disaster recovery cloud.
VMware data disaster backup mode selection
1. Hot-Add backup mode, need to install UCACHE disaster recovery cloud agent
Use NBD, NBD-SSL, Hot-Add mode to back up virtual machines on the ESXi platform. The backup client can only be the virtual machine on the target platform, and use Hot-Add mode to only back up the ESXi Server where the client virtual machine is located. To the virtual machine on the storage.
If there are multiple ESXi platforms or multiple data centers that require virtual machine backup, it is recommended to configure a client virtual machine on each ESXi platform and then use Hot-Add mode to back up.

2. VMware SAN structure data backup mode is VMware agentless backup mode
The ESXi platform selects the SAN mode when storing its virtual machine disk on FCSAN or iSCSI SAN.
If the customer environment is the same, using SAN mode backup will greatly increase the speed of backup. To use SAN mode for backup, two conditions need to be met:
1) ESXi platform virtual machine is stored on FCSAN or iSCSI SAN
2) The physical machine where the UCACHE disaster recovery cloud agent is installed must be able to access the FC SAN or iSCSI SAN where the virtual machine storage of the ESXi platform is located.

UCACHE disaster recovery cloud VMware virtualized backup operation steps:
1. Enter the web console to create a virtualization platform
The system administrator logs in to the web console, enters [Resources] → [Virtualization Platform], clicks [Add], and selects [VMware Virtualization Platform].
2. Assigned to backup / restore operator
(Currently UCache cloud disaster recovery 100G is free to use, data compression, deduplication ratio: up to 7: 1, the actual 700G data means that after intensified block compression, and parallel deduplication backup is actually displayed on the UCache disaster recovery cloud platform Occupancy is only 100G.)
VMware data disaster disaster recovery
UCACHE Disaster Recovery Cloud WEB management console browses data for automatic recovery. For VMware data recovery, if the data source virtual machine is still retained and the newly restored virtual machine also needs to be used, the network card of the newly restored virtual machine needs to be modified [including MAC address and IP Address] to prevent business interruption caused by IP conflict; if the source virtual machine is completely deleted, the newly restored virtual machine does not need to perform this operation.
