I’m an IT Professional but a newbie in Linux environment ,I can easily follow instructions
my question is how to create an exact image of my setup in clear Linux , like bare metal backup or VSS backup .
for example I used Acronis in windows , is there any soft that can I use in Linux which has the same features as Acronis ?
This seems like it’s a generic Linux question, and not a Clear Linux OS specific question. Have you googled around for solutions and answers?
There are many different solutions. You can make bit-for-bit images with dd and alternatives, for instance. You could use rsync for remote dumps/backups. There are literally dozens of tools that offer backup solutions available.
Again, there are dozens of methods here you can choose from, none are particularly specific to any Linux distro. Maybe you can explain how you expect to consume these images later on. Do you need to clone them to another system?
Something like this gives you a nice, compressed raw image of a partition:
