back up to NAS
 

Hey peeps, I spent all night trying to find a way to back up to NAS (ftp )from command line in linux(Redhat 4).I tried curl , but that is basically for one file transfers. I did the following for multiple files, but it didnt work
for f in /home/no/*; do curl --upload-file "$f" --ftp-pasv ftp://root:123456@44.44.44.44/backup; done

I tried mput -R but didnt work

Anyone have any ideas to do it best?

Thank you

any help or suggestion is good, i think i exhausted google.

If you provide more information about how the NAS is connected to you system, we can understand better what is possible and what not.

Right now, lacking information, I would recommend to mount the NAS on your file system, and run rsync, excluding /mnt, /proc, and sys. Much easier than ftp like solutions and you do incremental backups by default.

NAS , network attached storage, so its not connected to my system directly, its over the network , thats why I need to ftp in order to transfer the data.Sorry didnt state that.

NAS-es only accessible by FTP? I don't think so. For Windows machines I expect you can map drives on your Windows machines using SMB. Since many NAS-es run Linux internally usually you can mount these drives using NFS. This seems probable as FTP is also available. However if all else fails, you can install a SMB client on your machine and connect using Samba. Then the NAS has become part of you file system.

Double post, sorry

What NAS is it? Brand, type etc..

ok @klinkels, thats a good idea I will try that, never heard of that been done before, thanks for the input.

@kellemes, its a DLINK DNS-321 .

This is what jlinkels means, just mount the NAS like any other disk/partition you have on your system..

You may have to play with it a little to get it going on your system but this works for me..
This is on of my fstab-entries (/etc/fstab) for connecting to a Synology ds207+
Where /etc/credentials is a file holding login-data for the NAS...
Syntax:
You need to have "smbfs" installed.
(Don't know how to do that in RedHat)

ooo ok, didnt know that was possible, I get you now jlinkels , sry didn't before.But I cant seem to install smbfs for red hat lol, cant find it thorough google, all the info I found says its being replaced by cifs.anyone knows how to?

mount -t cifs //volume_1 /media/smbnas -o port=21,ip=799.79.49.69,username=st90

it ask for pass, but then I get mount error(22): Invalid argument

now I try :

mount -t cifs //76.73.48.66/volume_1 /media/smbnas -o port=21,ip=76.73.48.66,username=staiin,password=AAAAAAA


I get this mount error 112 = Host is down , I think I get this because I am trying to access across a different network.Not sure any help please?

First leave out the port=21. Port 21 is for FTP and that is not what you are doing here.

How do you mean the NAS is on a different network? Is it not part of your LAN? If not, ou should make sure there is a connection possible on port 445 and 137,138,139. If you are trying to access this over a public network I must discourage opening those ports though as it infers a security risk.

If the NAS is on the other side of a public network I recommend that you find out if the box does run Linux and if SSH and NFS are supported. IN that cae you can open a SSH tunnel and perform NFS connection.

In any way, NFS is to preferred over SMB and/or FTP as user permissions are handled correctly while they are not in SMB.

The manual does not indicate that the box supports any other protocols other then FTP and CIFS. If this unit is on a different network is it also behind a firewall/router?

Well the box does support NFS and SMB, it has port 21 open , so I decided to use port 21.Which other port am I to open then if not 21?

The box is in the same NOC , but on a different subnet/network.The box doesnt run SSH though only SMB and NFS.

I dont think its behind a firewall, but can ask the NOC if it is(No firewall system is in place on the NAS)
