Often you have to make on backup virtual maccine. And as usual, without wanting to spend money on additional products.

The following procedure is based on well documented script Ghettovcb.sh

I have not invented anything I just tried to summarize all the steps.

If you find errors the comments are there on purpose.

Prerequisites:

• SSH access to machines (if you have not enabled on ESX refer here )
• The program Putty
• The program Plink
• The program WinSCP
• A copy of the script ghettoVCP.sh

Installed on the Workstation Vs Programs

Copy the script on the machine using WinSCP ESX7ESXi

Spostat elo script in the first data store, usually Datastore1, because ESXi does not delete everything in datastore strova to reboot.

Cambite execute permissions in 644 with the command chmod + x ghettoVCB.sh

Create a file that contains the name of the machines which make up

• cd / vmfs/volumes/Datastore1
• Write: I vmbackups
• Press to enter the editing mode to insert Keyper there. write the name of the first machine to be saved and then enter the second and then press enter ..... then press enter.
• Press Esc to exit from editing mode.
• Type a colon ":" and then type wq and enter.

Now choose where to save the backup:

you can leave and save them locally via WinSCP every day

or mount an NFS datastore

Edit the script sesuenti linne, tlo script is commented very well you should not find difficult.

• VM_BACKUP_VOLUME = / vmfs / volumes / backup (this is the path to your NFS share)
• ENABLE_2GB_SPARSE = 0 (set it to 1 ise you want to split the VMDK infile 2 GB)
• VM_BACKUP_ROTATION_COUNT = 3 (number of backups to keep before deleting the oldest)
• VM_BACKUP_DIR_NAMING_CONVENTION (Leave it as it is)
• POWER_VM_DOWN_BEFORE_BACKUP = 0 (I'm going to 0 (zero) a live backup)
• ENABLE_HARD_POWER_OFF = 0 (I change to 0 (zero) to disable a hardware off)
• ITER_TO_WAIT_SHUTDOWN = 4 (I leave it as is)

Ok now go to the folder and run the script. / GhettoVCB.sh vmbackups to back up ......

You'll see a status similar to that avazamento below.

Completed backing up specified Virtual Machines!

At this point we have verified that everything fuziona go as we would like to schedule a recursive process.

We copy plink on our VirtualCenter or on an other machine if we use ESXi

We create a file with notepad called backupesx.cmd

with a syntax similar to the following

c: \ putty \ plink.exe root@10.10.10.1 -pw password "nohup ./vmfs/volumes/datastore1/ghettoVCB.sh / vmfs/volumes/datastore1/vmbackups> / & vmfs/volumes/datastore1/backuplog.txt"

where

c: \ putty \ plink.exe is the location where torvare plink

root@10.10.10.1 address is root @ ESX / ESXi server

. Poassword where pw password is the password of root sull'esx

./vmfs/volumes/datastore1/ghettoVCB.sh location script

/ Vmfs/volumes/datastore1/vmbackups file that contains the machines to be backed up

/ Vmfs/volumes/datastore1/backuplog.txt locazionedel log backup

Scheduliamo job in the scheduled tasks in the manner of windows operating system ....
