General :: OpenBSD - FreeBSD- Mac - Back Up All These Systems To An External Hard-drive Using Rsync
May 20, 2011
I have an OpenBSD and a FreeBSD system and a mac. I also have a Linux server. What i would like to do is back up all these systems to an external hard-drive using rsync when the external usb disk is connected to my linux box.If i format the external usb disk with cfdisk and the create a non-bootable ext3 file system on this external disk and create and put all the necessary public keys on the Linux box then from the BSD's or the mac issue the command:
Code:
Will this back up the entire systems so that they can be restored in the event of an emergency? I should store each OS just in a separate disk file of the external usb drive each time right? Because i would rather not have to format the external usb drive for each different OS. Would this work? and would the restoration command for these BSD's be:
Code:
I just need to know the basics. I'm sure given that i'll be able to automate the process. I don't want to clone the disks for forensics. I just want to have a way of restoring to a clean OS. This is the most basic question:All the howto's never mention whether or not you have to have an rsync server running on the machine your backing up to. So do you just push or pull from one end of the connection only or do you have to have a client at one end and a server at the other, as is traditional?

CentOS 5.2 64bit 2.6.18-92.el5xen. Use rsync with --link-dest for nightly backups, works well. Was recently asked to start weekly backups to an external drive for off-site storage. The regular syncing works but hard linking seems to be ignored. So the backup is long with no space saving advantage. Here is an example of the command being run:
rsync --stats -axzvl --numeric-ids --delete --link-dest=/mnt/DISASTERBACKUPS/austinBackups/backups/2009-08-21 /AUSTINBACKUPS/backups/2009-08-24 /mnt/DISASTERBACKUPS/austinBackups/backups/

My media library isn't huge, but it isn't tiny (~50 GB). Every month or so, I just manually copy ~/Music, ~/Pictures, and ~/Videos to my EHD, and delete the old backup. But this is far from ideal. It's pretty slow, for one thing (~50 GB all together). It also isn't versioned, so if I ever want to go back multiple versions, I'm out of luck.
Is there any simple, stable, incremental way to do this? I'm open to using traditional version control systems like Git for it, although I haven't used them before for anything other than code. Command-line is fine (especially if it's scriptable). I only need to back up these 3 folders--anything that's not media is stored in my Dropbox.

I have a 1TB USB external drive, currently formatted as fat32. What I need to do is copy two folders and all their subfolders, totaling about 500GB, to that external drive. The USB drive will have to transfer back and forth between RHEL, Windows XP, and Mac OSX computers freely.What format should I go with on the USB drive, FAT32 or NTFS?What rsync switches should I use? I know I don't want to use -a because I don't want any permissions restored. I'm guessing I'll have to run rsync a couple times to fully get all the files, so I need to be able to cancel an rsync, then have it pick back up where it left off, not start over and recopy every file again.

anyone shed some light into these errors I keep getting for multiple files when I run rsync in verbose mode to a FAT32 external hard drive?
rsync: stat "/mnt/usbdrive/Batch 2/od venezuelan" failed: No such file or directory (2)
rsync: recv_generator: mkdir "/mnt/usbdrive/Batch 2/joseph gangster" failed: No space left on device (28)
I have 588GB available on my external hard drive, and i'm only trying to rsync 200GB to it, so its not out of space or anything like that. I've tried rsync with -r -t --size-only --delete and -r -t --modify-window=1 --delete and both ways seem to give me the message. or should i just reformat as NFTS and start over? i already had another 200GB data set copied on here, was trying to add a second. its all JPG pictures.

Im using it in an attempt to backup all of the files off of my dead Windows xp Computer. Right now I am using the 9.10 live disk of Ubuntu and cannot get the program to recognize what kind of file system my internal hard drive is using. (A western digital 320 GB hard drive with partition 1 in NTFS and part2 in FAT32) I would like to be able to back up this drive onto my 1 TB Western Digital external hard drive that is also in ntfs.
Now here comes the wierd part, it won't read or recognize my interal and external hard drives that run those file systems but it will recognize and allow me to read, edit, and access all of the ntfs hard drives on my home network. I did some lurking and tried a tutorial for creating a mount point and on how to force mount a disk, but neither of my disks would show up in Places/Computer. So then I checked the /etc/fstab file and is says,
aufs / aufs rw 0 0
tmpfs /tmp tmpfs nosuid,nodev 0 0
Which I think means that it says I have no hard drives installed or connected to the computer. Yet when I go into Disk Utility it tells me the disk is there and asks if I want to format the disk into ntfs...

I am trying to install freeBSD on F14 (with LUKS encryprion). freeBSD doesn't detect hard-drive, probably coz of LUKS? Now what can I do within F14 to format harddrive and remove LUKS to get in a shape that I can install freeBSD or other OS.

I have never used rsync before, only DD. But from what I have been reading, rsync is better becasue it will basically mirror your hard drive, thus being able to run the cloned software from the new hard drive. My problem is I do not know what is the best commands or even the basic commands to use in rsync. I am trying to make an image from a external hard drive to a usb drive. That way my chances of messing up he original software is not as risky becasue I'll just restore the image onto another hard drive. Does anyone know the best script to have rsync make an image file of a hard drive and place it on a usb drive and then restore it?

As my proficiency with Linux improves slowly, I've been trying to find the answers for myself, but in this situation I must admit I find myself rather stumped. I have a perfectly nicely working Fedora 12 install on an 80GB SATA drive, and when it hit an error and wouldn't boot last week (easily fixed with fsck from the initial command line) I panicked and ordered a new 250 GB drive. It got here and I might as well use it, I thought to myself, so I went about trying to figure out how to move my install without having to reset all of my settings, programs and so on. I didn't want to mess with dd because I'm not so so clear on resizing my partitions once the copy is done (if someone thinks this is a better idea I'm open to suggestions.) After some poking around I found this set of instructions which I attempted to follow to the letter, but hit some snags. I understand this thread I am referring to may be a bit outdated, which is why (I assume) I hit a bump here
Code:
# mount /dev/hdy1 /boot
mount returns an error demanding I specify the file system type. At a loss, I barreled on until
Code:
[Code]...
To summarize, I partitioned and mounted my new drive using fdfisk and the instructions provided above, then used rsync to copy over all of the files, so as far as I know the new drive is ready to go, just not yet bootable. Opening the Grub.conf file in Kwrite (as root) returns a blank page. What do I do now?
As a side note, you can see that I am not too squeamish about the terminal, so I would prefer to find a "command line only" solution to this relatively simple (?) procedure.

I've picked up an HP Simplesave external drive. It comes with some fancy software that is of no use to me because I don't use Windows. Like many current consumer-targeted backup drives, the backup software is actually contained on the drive itself. I'd like to save the drive's initial state so that I can restore it if I decide to sell it.
The backup box itself is somewhat customized: in addition to the hard drive device, it presents a CDROM-like device on /dev/sr0. I gather that the purpose of this cdrom device is to bootstrap via Windows autoplay the backup application which lives on the disk itself. I wouldn't suppose any guarantees about how it does this, so it seems important to preserve the exact state of the disk.
The drive is formatted with a single 500GB NTFS partition. My initial thought was to use dd to dump the disk (/dev/sdb) itself, but this proved impractical, as the resulting file was not sparse. This seemed to be because the NTFS empty space is not filled with zeroes, but with a repeating series of 16 bytes.
I tried gzipping the output of dd. This reduced to the file to a manageable size — the first 18GB was compressed to 81MB, versus 47MB to tarball the contents of the mounted filesystem — but it was very slow on my admittedly somewhat derelict Pentium M processor. The time to do that first 18GB was about 30 minutes.

I am using Asus eee PC model 1001P and I am running ubuntu netbook remix on it. I have a 160 GB hard drive. When I was installing ubuntu I assigned only 50 GB for it, thinking that I will use the remaining partition for windows. But right now after using UNR, I don't want to use windows at all. Is it possible that I can assign the remaining 100 GB unassigned partition back to Ubuntu without reinstalling the whole operating system again?

I've been thinking about it and I have a few ideas how I could do this...
I could always just image the drive...
Code:
dd if=/dev/sda of=/media/EXHD/bakup_$(date +%F).iso
Also; I could use rsync...
Code:
rsync -auv --delete / /media/EXHD/bakup_$(date +%F)/
[Code]....
I've been doing mostly "dd" images...but was wondering if I'm just wasting time backing up a mostly empty HD (256GB and only 5% is used...so dd-ing seems like kinda of a waste).

but I have literally just starting using Linux (Centos) in the last week or so. I am using a standalone PC that is not networked, and as I will be downloading and generating a lot of data on this machine, I would like to regularly backup onto an external hard driveIdeally I would likethis to happen automatically as there will be other people using the machine.There seem to be many different ways of doing this, and I am getting a bit confused about the best method to use.

I have a Seagate external hard drive and I want to use it to back up my home server since it runs Ubuntu 6.10 and the upgrade to 10.10. My problem is that I am not able to format the drive to use it. I can not change the permissons or if I try to format I have all sorts of trouble. I have tried doing it on the home server running 6.10 and another pc running 10.10 and had no luck. Is there a better way? I have even tried chmod and chown with no luck.

I am trying to recover files off a 3.5" IDE Hard Drive that had Windows ME installed on it. I have access to a MacBook, Windows XP Desktop PC, and a cd with Ubuntu 8.10 on it.
Attempts:
1) If I make the HD the only primary master HD it won't boot up.
2) If I make it a slave drive it won't boot up.
3) I purchased an external enclosure from Radio Shack which turned out to be crap and online reports supported this conclusion. I got nowhere with that thing. Bestbuy doesn't sell 3.5" IDE enclosures.
4) By using an IDE / SATA to USB kit, I am able to connect the HD to the PC via USB cable. XP will detect the drive, however the HD will not my displayed under "My Computer" nor "Disk Management".
Onto linux (this is where I grabbed the Ubuntu cd):
5) When connected, the HD will show up under "Computer" as a "USB Drive". When I double click on it I get the error "Unable to mount location Can't mount file".
Allow me to show you some commands I ran:

I was in the process of backing up data from my hard drive to an external usb drive when the drive suddenly became read only. Does anyone know how I can make it read/write again? I am using Debian Lenny and the drive is ntfs formatted. I have another ntfs formatted usb drive that is not effected in this way.

Ubuntu 9.10 recognizes my Freecom 120gig external hard-drive (when it's plugged in) and I can manage its contents OK - except via the command line. I don't seem to be able to find its path-name. See below:

I have a mini ITX computer that runs a software that I have been trying to clone to another hard drive as back up. When I do clone it, it is the exact same copy down to every byte. When I try to boot from the cloned hard drive, it starts booting, then displays some text:
Then is says some of the files are not found including a encryption signer key not found.
I do no know the next step I need to take. Is this becasue it is running off a different hard drive? I do not understand a bzImage too well, but does it have anything to do with that file?

I recently had a laptop die on me. I, of course, then to recover the hard drive. I wanted to install slackware to a partition on my drive, so I can have a linux distro with me( also I have a FAT32 partition for shared space) I have a Slackware 13.1 disk one (which i need, since I don't need a graphical environment or anything), and proceedd to follow setup program. I have a 5GB '/' partition, a 10GB '/home' partition, and a 2GB swap partition. My ROOT partition is bootable. The setup program seemed to complete succesfully, but it won't boot. When I choose to boot from my hard drive (in the bios), it reverts to the slackware disk, if present, or the standard windows drive.
I installed LILO to the superblock of my external, because according to the setup the MBR option installs to "The MBR of your first hard drive", and I wasn't sure if that was right, since my first hard drive is my windows one. Since i'm not even seeing LILO, I think it has to do with installing to the superblock. I want to be able to boot a basic linux distro if needed from whatever computer I want. I'm not sure if slackware was the right choice, but it was one that I had worked with installing before, and knewthat you didn't necasarraly have to instal all the graphics stuff. I just want a shell. Sorry if my question sounds retarted, I'm new to the whole "Multiple drives, and operating systems" thing

In Ubuntu 10.04 all I had to do was turn on my external hard drive and it would automatically be detected and mounted. I just switched over to Ultimate Edition, which I think is Ubuntu 10.04 with a lot of stuff added on to it. The funny thing is when I turn on the external hard drive it doesn't get mounted, and I don't think it's even being detected. I looked in gparted and it doesn't show up there. If I boot into Ubuntu 10.04 and turn on the hard drive it still gets detected and mounted, so there's nothing wrong with it. Ultimate Edition can detect other things connected to USB, like my iPod, so I'm wondering why it can't detect my hard drive.
Edit: When I do tail -f /var/log/messages and if the drive gets detected, this is what it says:
[ 230.520892] usb 1-2.4: new high speed USB device using ehci_hcd and address 6

I administer a remote server via SSH that runs CentOS 5.5. I have been unsuccessful in all my attempts to write to two different external USB hard drives with a single ext3 partition when logged in as root.
When attempting to create a "test" directory I get one of two messages:
Quote:
Both drives *appear* to have filesystem issues. When I run an fsck on either drive, I get:
Quote:
Keep in mind this is a newly-formatted, empty drive.
Not putting stock in the odds that I've had two hard drives (different sizes and brands) with the exact same hardware problem, I'm going to assume this is a software issue, although maybe it isn't. Hence, my post in "Linux - General". I've heard talk elsewhere of controller (chipset) issues coming into play. Is this valid?
Okay, here's the information you'll need to make a diagnosis....
Here's the output of a "df -h" command:
Quote:
Here's the contents of my /etc/fstab:
Quote:
Here's the output of "cat /etc/mtab":
Quote:
Here's the output of a mount command:
Quote:
Here's the output of fdisk on the device in question:
Quote:
The number of cylinders for this disk is set to 48641.
There is nothing wrong with that, but this is larger than 1024, and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs (e.g., DOS FDISK, OS/2 FDISK)
Command (m for help):
I've got someone with access to the box if necessary. But it might take days to implement solutions since this isn't his full-time job. Remote solutions are, therefore, preferable.
