Cronjob format

I really don't know what I am doing so I am looking for some help...

Goal: backup /public_html but exclude directory A , gzip it and move it from the root directory to directory B.

( have very many, very large sermons in mp3 format in directory A which I don't want backed up as I already have them locally.)

Attempted:

Code:

date=`date -I` ; tar -zcf backup_$date.tgz ./public_html --exclude=/home/username/public_html/directory A > /home/username/directory B/backup_$date.tgz

Result: makes a bu and puts it in the root dir, but does not exclude dir A. Also puts a bu file with the same name in dir B, but it is empty. I don't know for sure that dir A is not being backed up, but the bu file is huge (+800MB) and this site is just a joomla site with a lot of media files in dir A - it would not be so big if it was excluding dir a. I think the job is timing out before it completes since attempts to unpack the tgz file halts before done saying it is broken. , but a test on another account w/o large files showed the "excluded" folder is indeed being backed up.

If someone could explain what I am doing wrong I would appreciate it.

Thanks

Ok, I don't really need to move it to another dir so here is what I tried last but it still doesn't work:

date=`date -I` ; tar -zcf backup_$date.tgz --exclude= "/home/crcheek/public_html/components/com_sermonspeaker/media" ./public_html

I would fully qualify where you want the tar file to be created. Glad you got rid of the redirect of standard out.. Wink

I would think this should work.

Code:

date=`date -I` ; tar -zcf <<path to directory B>>/backup_$date.tgz ./public_html --exclude=/home/crcheek/public_html/components/com_sermonspeaker/media

If not, try changing your --exclude to:

Code:

--exclude=./public_html/components/com_sermonspeaker/media

Also, the way I do this on Linux is the following (slightly modded - I put the script in my /etc/cron.weekly so that I get a weekly backup).

Code:

#!/bin/bash
#!/bin

Feel free to "steal shamelessly" if it helps you. Yes, I blanked out just a few things with "********", but you get the point.

Thanks, Montego. I will try to get to that asap, but I am worn out. Just married off my last daughter today.

Oh my.

That is not only a tiring process, but a sad day to boot I'm sure. However, knowing you, you've "trained her up in the way she should go"... Wink

Congratulations as well as my sympathies my friend.
