Azure Backup 1700 GB limit of initial Buckup
The first time Buckup expands the vhd file, but the upper limit of the vhd file is 1,700 GB, so if this limit is reached during backup, an error will occur.
The next retry backup job will change the file from .vhd to .vhdx and raise the limit to 54 TB, so the same error will not occur.
Please create from the beginning with a .VHDX file and change it so that the upper limit is 54 TB. Thank you.
