VA for AIX compression

[philfreund]

When compression in enabled for the AIX agent, does it just blindly compress everything or is is smart enough to not compress already compressed file types such as .zip and .gz? I've generally found that compressing already compressed files make the resulting files larger.

Hello,

I've generally found that compressing already compressed files make the resulting files larger.

do you maybe have an example for that? Or do you see that your Veeam backups are larger than your source?

I just tested it with a pptx file which is a zip file in the end. The pictures below do not confirm your thesis




to answer your question: the Veeam Agent (no matter which one) compresses everything.

Best regards,
Hannes

Hi,

All Veeam Agents compress backup file blocks, not the files that you back up.

Thanks!

Thanks for clarifying that. I tried running the same full backup job both with and without compression turned on against a large filesystem containing compressed files. The runtime was marginally faster without compression and size of the resulting backups were almost exactly the same.
