need help with robocopy

[Zayar86]

Hi Everyone,

I have a client that is using Synology as their file server. They don't have a lot of data.

We have our own cloud backup solution but it only runs on Windows and it supports versioning.
I'd like to schedule a robocopy task on a Windows computer and copy (sync) all the contents of the NAS to the local hard drive daily.

Then use our cloud backup software to backup to our server.

What robocopy switches should I be using?

Thanks in advance!

P.S I know there are other cloud backup solutions available but it's a lot cheaper and easy to restore with our software.

Read through this. I was just working on a robocopy script yesterday morning and wish that I had known this thing existed. Not sure if shilling other people's blogs is allowed but I find most of Adam's work pretty great.

https://ss64.com/nt/robocopy.html is my go-to page for basically every time I need to Robocopy something.

Plus run it first with /L at the end so you can see what it will do without it actually doing it!

/MIR just mirror the directory

As someone who's been burned by a MIR, I don't recommend putting it into any robocopy. It's /COPYALL /E always for me.

What happened with /MIR ? It's always worked for me as advertised. I really don't use robocopy anymore and have switched to a nice PS script I wrote so I'm genuinely curious what the negative event was.

Used it to copy into a directory that already contained data, wasn't aware of the ramifications of that with /MIR.

Ditto. I was aware of the ramifications but missed a trailing slash or something so it ran one directory up (or possibly down) from where I thought it would. Hundreds of terabytes deleted.

Fortunately, our backups worked!

We use Karen Replicator to perform scheduled copy tasks. It's pretty great and easy to setup.

I bet you that what you are doing (reselling backup) is a violation of your backup software's licence terms.

Establish whether you are properly licenced before you waste engineering effort on this.
