System Requirements And Compatibility
3.4.1.b
The VMs must be using basic disks. Dynamic disks are not supported
The VMs must use an MBR partition. GPT partitions are not supported.
HotAdd Disk Requirements
When using the HotAdd transport, the following disk restrictions and requirements apply.
HotAdd only works on SCSI disks. IDE disks and vRDMs are not supported.
HotAdd cannot be used if the VMFS block size of the datastore containing the virtual machine folder
for the target virtual machine does not match the VMFS block size of the datastore containing the
vRanger VM. For example, if you back up a virtual disk on a datastore with 1MB blocks, the proxy
must also be on a datastore with 1MB blocks.
3.4.2
Dynamic disks are not supported
GPT partitions are not supported
Password Security Setting Policy
Weak passwords compromise system security. When you create and update passwords in vRanger,
follow as many of these guidelines as your environment allows:
A password should not include a significant portion of a user or account name. A password
should be at least six characters long and should contain several characters from these
categories:
Lowercase letters in English (a-z)
Digits (0-9)
3.4.3
Uppercase letters in English (A-Z)
Non-alphabetic characters (for example, $, !, #, %)
