Seeking backup script

[eemaestro]

Did anybody save a copy of my backup script (BASH) for backing up files?
Can't remember if I posted it here or not.

I remember seeing a backup script a while ago, so I think you did post it here.
Unfortunately I don't have a copy.

If you use the Forum search filling in both "backup" as keyword and "eemaestro" as author, there are a bunch of hits.

You can also use 'View your posts'. It's at the top of every page.

Thank you, lucky9. That is a helpful tip. I couldn't find the script. i guess I never posted it. I rewrote the backup script. If anybody wants me to post it, say so, and I will.

Go for it.
