Hello Guys,
Hope all are healthy and safe and enjoying the present. If you are healthy and safe and still not enjoying the life then start enjoying it :) This was today's Gyan!
I wish that as VMware has this snapshot feature, life also should have this feature. When you feel that I am most content, successful and happiest then take snapshot and save it somewhere and in adverse days, revert the snapshot. Unfortunately, it doesn't happens. Because whatever happens in life, happens for once and get implemented permanently. No more Gyan! let's start the main discussion :D
So, today's topic is "Snapshot". Why I am writing about it because I found still many guys have many doubts about it. Is it that mysterious? Interestingly, many interviewer ask about snapshots. Don't worry, I guarantee that who follow my blog and read my posts, they will not be having any doubt about snapshots after this.
Now question is, it is already covered on web then what's new here?
Seriously, you think that all about snapshot is covered of web. Then you are thinking wrong. Let me tell you that how vCD snapshot works, there is no formal documentation on it from VMware as well and I don't trust anyone else words until and unless he\she directly from VMware or there are some practical proof of the same. I recently (On 25 Sep, 2020) requested VMware to create KB or a formal documentation on the behavior and they accepted it.
Another point is, lots of snapshot information are there on web but scattered. I guess you don't have any blog which is having A-Z solution\definition\explanation of snapshots. Please comment if you have any such website\blog. I love to see some.
As of now, I am creating questions till end of next week that is 2nd Oct, 2020 and then will write answers about it. If anyone has any question, want to clear any doubt can comment here and I will include the question and will definitely provide answer\explanation for that.
Q1 : What is snapshot? Quite basic
Q2 : What is snapshot with memory and quiescing during snapshot.
Q3 : What is background process when we take snapshot? Many guys fails here
Q4 : What is background process when we revert the snapshot? Sound interesting. isn't it?
Q5 : How older and big snapshots impact virtual machine performance?
Q6 : Snapshot behavior on thin and thick logical disks?
Q7 : How VMware Cloud Director works with snapshots? This is going to be interesting.
Q8 : How to automate snapshot creation and deletion process?
You can ask me to add any real time example which you have seen in your environment.
Help me to add more questions here so I can help you with answers.
Thank you,
Gautam Johar
