I am trying to work out the storage requirement for my vm backup.
I got all the vmdk file size which is about 10TB. I know that most of the vm backup software uses snapshot technology to backup the VM. But do not know whether they backup entire vmdk file.
Do I need 10TB or less?

It uses the sanpshot technology to quiesce the disk. That means it will stop writing to the main VMDK while the backup is happening.
But the Whole VMDK is backed up depending on the level backup you have chosen. if you used machine level backup then you will need the space of the actual machine space.
Of course if you use technologies like de-duplication it will reduce the space but classic backup you will need 10TB of space.

Abhilash Hb comment above is 100%. Just wanted to add that if you use point in time backups you will need even more than 10TB. The amount of space in addtion to the 10TB full backup will be calculated as you rate of change between your backup points.

I request you to re-assign the points. Both of them are correct answers. Point in time backups are not usually taken and its a special case which has to be considered and not exactly the answer for your question but an assisting comment.
