Ubuntu Servers :: Backup Fileserver To External HDD, EXT3 Or NTFS?
Jan 23, 2010
After a near miss with my 1.5TB, RAID5 file server, I have decided that I need to backup my data to an external hardrive periodically.I have been looking at rsync but the question I have is: Do I format the external hard drive in EXT3 (the sameas my fileserver) or NTFS?All my main machines are Windoze, but the file server is Ubuntu with a samba share.If my server ever went belly up, I would like to be able to access my data from the external hard drive. I guess if it's in EXT3 then windows would be clueless... I would either need to fix the server pronto or access it with a live CD or something.What would I lose if I used NTFS instead of EXT3? I think I would lose permissions and possibly ownerhsip information - are there any other issues?

I need backup software that will backup to a NTFS external disc. Do any/all of the back up softwares work (ie resync)

I have been trying to use fstab, writing a script in /etc/init.d to mount my external ntfs usb drive. I have had absolutely no luck and I have tried just about every solution I could find on the web except for writing a udev rule which I have never done so I am not exactly sure how.
My solution for the interim is to put the mount command in the rc.local file. That works, but I don't understand why I can use fstab to mount it. Putting it in the fstab gives me errors like "unknown file system" or just "An error occurred during mounting of drive" and then the booting stops. I tried using both ntfs and ntfs-3g.

I'm running a cron job every night to dump a MySQL database to an external hard drive. It works, however when I check on it the following morning the external is no longer mounted and the XFS log file is corrupted. If I run
Code:
xfs_repair -L /dev/sdf1
It works, but then I get these issues:
Code:
XFS: Filesystem sdf1 has duplicate UUID - can't mount
I can reset the UUID, but it's difficult to have to do this every day.

I am trying to restore an NTFS partition from a backup and I need the new drive to have the old (dead) drive's UUID (which I recorded).I really really really cannot use the option of changing fstab to mount using a new UUID, for this case I need the old UUID that existed on the other drive.Is there some ntfs equivalent of tune2fs that'll let me change the UUID on an ntfs partition?

i am taking another stab at this. The last time i attempted it, it seemed like everyone had a different way to do it, but nobody could give me an answer on how to do it...
I currently have a Domain Controller Running sme server and a domain controller, using ldap as a backend. I have two file servers runing ubuntu 10.04. My overall goal is to have it so when i create a username on the domain controller, it is then automatically copied over to the fileservers. This way everyone will have their own username and password to access the fileservers and ill be able to track what people do on the fileservers.
The next necessity is for me to be able to apply permissions to the folders on the fileserver based on the users that are created on the domain controller.

I am very new to Ubuntu (any Linux) evironment. And it has been a long long time since I have dealt with seting up servers. I have done alot of searching but haven't found exactly what I THINK I am looking for.
I want to create a file server (I have created my Ubuntu server cd) and add it to my home network (all windows pcs). I need to be able to access it when away from home ( I work away from home mostly). I will be accessing this with a Windows 7 laptop.
What do I need installed on the server? Samba for the file server part. What else for the remote access? I also would rather not access the data via FTP. I would like it to come up as a drive in my Windows Explorer. If not, I remember back in college (20 years ago) when I could open a little window (XWindow maybe) on the other server.
An issue I see that might not be an issue. I have a static IP from my ISP. It comes into my home via their modem. I attach to the modem with a router. All my laptops connect to it wireless and this server will be wired. How do I hit the server and not one of the laptops with only having the one IP address? Each of these plus my external harddrive and printer have their own internal IP address' that I have assigned.

I recently upgraded my ubuntu samba fileserver to 10.04 along with increasing the size of my RAID 1 /home directory.I am using the same smb.conf file setup I have used on intrepid ibis setup and hardy heron setup before that.On my new setup, I can see the ubuntu server on my windows 7 machines, but I can't see the shares and can't access them.In checking the logs (/var/log/samba), one log continues to look for a printer share from one Windows machine that I have not set up on samba yet.
I have found a few people who have reported similar problems online, even a few who have filed bugs, but then they say "my computer started working suddenly. I don't know what happened." so they closed the bug. or "my computer started working after I rebooted my machine." I have rebooted all machines on the network. That doesn't fix it.

Just installed 11.3 on my computer, however when I connect an external NTFS harddisk I receive an error message. When I open dolphin to connect to an internal NTFS partition I receive the message:
org.freedesktop.Hal.Device.PermissionDeniedByPolicy: org. freedesktop.hal.storage.mount-fixed auth_admin_keep_always <--
Anyone having an idea how I can fix this?

New fun from M$, we have started to test Win-7 on a few machines, and while it worked flawlessly in XP, Vista and Win-7 beta, logging on to the share (AD) from a Win-7 RC doesn't work.

I am trying to copy the contents of an external NTFS hard drive to my internal ext3 drive. Ubuntu 9.04. The transfer starts, then slows, then grinds to a complete halt, and has to be ended, causing icons on my desktop to disappear. Then the hard drive needs to be unplugged, then re-plugged to register in ubuntu again. Sometimes this happens first time, other times it will not register after many plug in - out cycles. Small files will copy across successfully while still in the "slowing down" phase, so I don't think it is a permissions problem. On the occasions the ntfs HD will not register in ubuntu, it makes a clicking noise when started, then spins down to silence. Could this indicate a hardware error, or is this ubuntu giving up after failed attempts to recognise it?
When trying to run files directly from the NTFS hard drive (when working correctly), it runs fine with no problems.I currently have this device plugged in via sata - usb adapter, but the same problem happened when this drive was an internal. I had planned to move all the files from the ntfs drive to my ext3, then format the ntfs drive to ext3 and copy the files back, but it looks like it's not meant to happen. Next time I can actually get ubuntu to pick it up and mount it I will try the enabling of DMA (as seen in another post), and trying to copy with rsync instead of nautilus (as seen in another post). Is there anything else it could be

I'm using a dual boot system with kubuntu 10.10 and windows vista.When I try to copy files from kubuntu to a windows drive, I see no problem.But when I retsart to windows usually I can't see my files. Once or twice I have seen files I copied in kubuntu. The strange thing is that when I go to kubuntu again, I don't see files I have copied in windows drive.

I'd like to set up a fileserver for myself and a few trusted individuals. I'm computer savvy and I use various linux servers frequently for work, but this is my first time trying to setup my own. Is it possible to have a Samba server setup so it is both secure and facing the Internet? Two questions:
Will opening Samba ports make my default Ubuntu server particularly vulnerable to penetration? More than having an SSH server running? Does Samba/ can Samba be configured to encrypt traffic or is it sent plainly? If so, does Windows and Mac support this secure communication?
If not, what would you suggest? I'd like to achieve something like a network drive and at a difficulty level that my parents could use this if they really wanted to. I will be storing things like financial information and tax returns, but no weapons-grade secrets.

Long story short, my Windows had a fatal crash the other day and since I couldn't find the installation disk, I burned the Ubuntu 9.10 disk image to a CD at a friend's place and installed it on one partition of the hard drive. The other partition contained tons of Windows programs and documents in an NTFS system. Ubuntu is cool and all, but when I finally found the Windows disk, I wanted to reinstall it for dual-booting, to use some programs that don't run well in Wine.
To keep some documents safe and not waste any CDs, I moved them over to the Ubuntu partition before installing Windows. As experienced ubuntuists know, the slightly clumsy Windows installer erases GRUB in the process, and it's recommended to install Windows first. So, now I ended up with a working Windows partition and an Ubuntu partition with all of the stored data, which I can access via guest status with the burned CD.
Here's the catch though - as a guest and without Linux properly installed I can't move anything I moved to the Linux partition from the Windows partition back anymore. All the folders have a little X on their top corner. I'd be glad to reinstall Ubuntu now, but I must know how to keep all that tranferred data safe. Can I keep it there during the reinstallation? Should I install Wubi on Windows and access the stuff through it?

Using a small hard drive (180 GB) dual booting windows XP for gaming and Ubuntu 9.10 for my other stuff during install I didnt know how much of each partition i would use, so i did 50-50 1 for ext3 and one for NTFSHowever after awhile it seems I have run out of space on my NTFS and have tons of unused space on my ext3.What I am wanting to do is shrink some of that ext3 down and give it it NTFS, I did a little searching and found a couple of old posts but I was a little sketchey on em. Simply looking for some personal Methods or Tools you have used and a starting point of how to use them.

Im currently using windows 7 and I want to shift for Linux. So i thought to start from Mandrake-free. My current filesystem is NTFS which full of windows extension documents. Those capacity is almost 200GB.but im not in a position to backup everything. i got to know from forums that linux perform well in ext3 file system. so i wish to go for ext3. is there any ways to shift FROM,win7 TO mandrake AND
ntfs TO ext3 WITHOUT BACKING UP CURRENT DOCUMENTS ASWEL AS WITHOUT LOOSING ANY OF MY WINDOWS BASED DOCUMENTS.? and i got to know that in a single harddrive(eg 250GB), Its not good for the harddisk to have different type of partitions (eg 50gb of ext3 and 200gb of NTFS). if i used like this will my harddisk got crashed? because this happened to me 4 years ago when i was trying to install winXp(in ntfs) and Redhat(in ext2) in the same hardisk. i was working initially. but was in 2 days that HDD got crashed.

I've lost my admin password on my current Windows OS and would like to install Linux Ubuntu or a similar user-friendly distro of Linux alongside, see how that goes and possibly reformat my PC with Linux as I was told it would convert NTFS formatted drives to ext3, not delete them.

There were some files residing on my ext3 file system, using Ubuntu as my linux distribution. Yesterday I formatted the hard drive using a windows install CD, rewriting it with a new NTFS partition. I'm willing to restore my personal files deleted due to this format.

I've been trying to figure out how to move /home to the other partition that exists on my computer, however it's ntfs and turns out it's impossible to move my /home there. So how do convert that ntfs partition to ext3, I don't mind loosing data that's in that partition. [url] is the partition I'm talking about. So what's the best way to do it ? If you write what commands I should use please include partition names.

A friend of mine and I bought an external hd (WD Elements 2TB) and formatted it in ext3 as root. Now we want to use this hard disk in more than one systems with different usernames. So we did "chmod -R 777 /media/ VolumeLabel" in all the systems.But we want the hd to pass around. So its a little bit inconvenient to do chmod all the time. So what should we do to make the access for the hd universal in all the systems that we plug it in?

I have a external HDD with eSATA and USB connectors available. I want to use this HDD to store my backups. The HDD should be encrypted (my main system is as well).
So here is what I did so far:
1) I used the following code to create the encrypted LUKS partition with EXT3 Filesystem:
Code:
cryptsetup -c aes-xts-plain -s 512 luksFormat /dev/sdb1
cryptsetup luksOpen /dev/sdb1 luks
mkfs.ext3 /dev/mapper/luks
The system always hang when I executed the "mkfs.ext3..." command, so I switched the HDD from eSATA to USB and then it worked fine.
2) When I switched on the ext. HDD the first time, the drive was recognized automatically and Nautilus asked for the password. I typed it in as checked the checkbox to remember the password in the future. For the backup I use a nice script that I found in another forum, where I can define a mountpoint and then the script will check for previous backups and only make a incremental backup based of the latest version. The script also mounts the drive automatically. In order to always have the same mountpoint, I want to make an entry in the /etc/fstab using the UUID of the ext. HDD.
Whatever I tried, it doesn't work. What am I doing wrong? Here is my current /etc/fstab
Code:
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc defaults 0 0
# / was on /dev/mapper/ubuntu-root during installation
UUID=2ea47421-73ce-4c66-9606-8a1db81ae640 / ext3 relatime,errors=remount-ro 0 1
# /boot was on /dev/sda1 during installation
UUID=dbdeb793-1d4e-43ea-8986-7b37fdbc9674 /boot ext3 relatime 0 2
# /home was on /dev/mapper/ubuntu-home during installation
UUID=42702091-83e6-43eb-aad1-108f43eedf9d /home ext3 relatime 0 2
# swap was on /dev/mapper/ubuntu-swap during installation
UUID=e225bcf9-908b-4226-a963-6b02ee658df1 none swap sw 0 0
/dev/scd0 /media/cdrom0 udf,iso9660 user,noauto,exec,utf8 0 0
# Eintrag wegen iPhone
none /proc/bus/usb usbfs devgid=125,devmode=666,nodev,nosuid,noexec 0 0
# external HDD
UUID=913977f7-8fa6-416f-af79-b5f913b68f53 /media/backup-hdd ext3 noauto,users 0 0
I made the "none /proc/bus/usb..." entry because it was recommended to ensure correct behaviour of the iPhone. Not sure if I need it though.
I created the mountpoint with this command:
Code:
sudo mkdir /media/backup-hdd
Now it seems the mountpoints owner is not root - strange right?
Code:
2 4 drwxr-xr-x 3 michael michael 4096 2010-01-15 02:45 backup-hdd
How should I mount this drive correctly? It will be automounted as every USB device, but that should not be the case. I want the script to mount and unmount the drive.

I'm trying to format a 500 GB external drive with gparted in ubuntu 10.10 (I searched & didn't see this issue in the forum). I set up and formatted two partitions, one for fat32, and the other with ext3, which appears to format ok, but I can't use it. Both partitions show up and appear to mount, but the ext3 partition won't accept activity (make new folder, copy in files), while the fat32 partition works fine. Both partitions show up ok when I query in terminal "sudo fdisk -l"

I have a scheduled backup to run on our server at work and since the 7/12/09 it has be making 592k files instead of 10Mb files, In mysql-admin (the GUI tool) I have a stored connection for the user 'backup', the user has select and lock rights on the databases being backed up. I have a backup profile called 'backup_regular' and in the third tab along its scheduled to backup at 2 in the morning every week day. If I look at one of the small backup files generated I see the following:
Code:
-- MySQL Administrator dump 1.4
--
-- ------------------------------------------------------
-- Server version`
[code]....
It seems that MySQL can open and write to the file fine, it just can't dump

I have 2 external drives that I'm using for movies and they're both formatted to fat32. The problem I'm experiencing now is that some of the high quality mkv files are not able to be moved to the drive because of fat32's limitations.
I'd like to convert to ext3 (or 4) and I wanted to check to see if I can do it without having to reformat and without loss of data.
