Script to create archive using powershell and 7zip

Question

We have several servers that write log files to C:\\Logs on a daily basis. Every month, a script is supposed to run to identify files older than 30 days, archive them, and delet

Answer 1

After reading some more and using the scripts and assistance posted here, I came up with something that does what I need it to do. I'm sure there are better ways to go about it (like adding more logic and if/then statements) but it's good enough. I might revisit this script when I get better at scripting powershell. Here's what I got...

#Network folder where archive will be moved and stored
$newdir = "X:\your folder\$hname"

#Archive log entry
$log = "c:\logs\"+ $today + " " + $hname + " " + "Log Archive.txt"

#Files older than $Days will be archived and deleted

#Only files with this extension will be archived and deleted
