Overview
fastcopy.py is a python script for
VMware ESXi 4.0 - 5.x that can be used as a replacement for "cp -R" to copy Virtual Machines.
fastcopy use
cp to copy
normal files but use
vmkfstools to copy
.vmk files.
Because
vmkfstools is 10 to 20 time
faster to copy such files, you will see a big difference.
When copying
.iso files you will not notice any difference !
The typical use of fastcopy.py is to copy multiple directories containing VMs to a target directory.
fastcopy.py don't handle recursive copy or simple file copy. Sources and target must be directories.
Usage
For example top copy one VM to a new directory :
./fastcopy.py /vmfs/volumes/SATA1/windows2008 /vmfs/volumes/NEWSATA
or if you want to copy multiple VMs, just list all VM directories. The last one must be the target one.
./fastcopy.py /vmfs/volumes/SATA1/windows2008 /vmfs/volumes/SATA1/linux /vmfs/volumes/NEWSATA
Installation
Cut&Paste script below to one of your
datastore and don't forget to make it executable using
chmod :
chmod a+x
