Backup to USB HDD
 

Hi guys I got this issue relate to doing backups in Linux, I manage to get a backup working every night; it is now stalled under user1, backup.

I manage to connect my usb hdd and gets it working using this link http://www.linuxquestions.org/questi...-point-511917/

Now the question is... how do I get the file into the portable HDD, I mean right now, I can do it manually every day, but I was hoping I can do it automatically I hearing people telling me using a script or some sort? Can someone give me some sort of idea of how to get it started?

many thx

Well how are you doing the backup ? Just add a line to the end of the script that copies the file to the USB hard drive. Or using udev rules, make a rule that runs a script every time you plug the disk in. The script copies the file across.

I tried to back up and this is the msg I get.

Mon Aug 23 23:00:29 EST 2010 Backup Started
cp: cannot creat regular file '/media/disk/xxxxxbackup.tar.z' Input/output error
Mon Aug 23 23:14:29 EST 2010 Backup completed.


I'm 100% sure that the usb device is mounted and it is working, I can write to and from it. But could this me mount point permsion issue? Because I only test it as root, and I normally just go in as root, but I set up the back up in user1. I know I'm kinda stupid.. don't know why I did this.

A permissions problem should not result in an an input/output error message. There may be more information about the input/output error in the /var/log logs such as syslog and messages or whatever your distro uses.

How is your external HDD formatted? If it is FAT32 then there's a limit to the maximum size any file can be (4GB IIRC). I think you may be meeting this limit.

I used this link http://www.ehow.com/how_1000631_hard-drive-linux.html to formatted the usb hdd to ext2

I'm just about to pull my hair out here, I cant figure out how to just get the files to the USB, and I'm new.. I don't even know where to look at for this problem.

and I dont think it's how i formated my hdd, coz I can still manually copy and paste the file into my usb hdd

Slap me around if I missed something obviouse

Please help

You still haven't told us what you did to start the backup when it fails. What command are you using ? Is it a script that starts it off ? When does the backup get run ?
You just said that you can copy and paste the files across, so how do you do it when it fails ?
What did you do that gave the output in post #3 ?

Is there any more information about the input/output error in the /var/log logs such as syslog and messages or whatever your distro uses?
