I have an external drive that I want to do backups to. Most times it goes great, other times the server gets real sloggy, and I do a 'df' and see I'm at 96% disk usage. What has occured is the disk failed to mount apparently, so the backup backs up to my local disk at /media/backups/
I have /media/backups in my /etc/fstab pointing to /dev/sdc1, but I think the external disk will sleep when not in use for long periods.
How do I make sure /media/backups is REALLY going to the external drive and not my local drive? Is there anyway to sort of test it BEFORE I write umpteen gigs to my local hard drive?
I have about 50 servers with at least 200 GB free on each host. I need close to 10 TB of continuous shared storage between almost half of the servers for a new app I building.
I was looking into buying a storage device but was wonder if I could get any use out of the free space on all the servers, grouping all of the free storage from the hosts into one reduduant storage array.
We have some servers that run in very harsh environments (research vessel) that need to have high-availability.We have software RAID 1 for some measure of resiliency, along with proper data backups (tapes etc), however we would like to be able to break out a new server and re-image it (including RAID setup) from a known good copy if the hardware completely fails on the production box. Simplicity of the process is a big plus.I am interested in any advice on the best way to approach this. My current approach (relatively new to Linux administration, totally new to MDADM) is to use DD to take a complete gzipped copy of one of the RAID'ed devices (from a live CD): ode: dd if=/dev/sda bs=4096 | gzip -c > /mnt/external/image/test.img then reverse the process on the new PC, finally using Code:mdadm --assemble to re-create and re-build the array.
Using the following command, I can access a windows 2008 server: rdesktop -u myusername -d mydomain -p - -fP -r sound:local -r disk:myhome=/home/myhome serveraddress
connection works fine, and to start with I can see my local disk "\tsclientmyhome" and navigate around + open files. If I try to delete a file or rename a folder, I get an Error 0x8007048F:The device is not connected.
After this, I can no longer access the local disk. It says: "\tsclientmyhome is not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions. Attempt to access invalid address." As I understand it, I should be contacting myself about permissions... Can anyone tell me what I need to do on my local ubuntu machine to fix this?
I have some issue with my amanda backup server, which is connecting with Scalar Quantum i500 via FC. I got the error as below 3 days ago. These dumps were to tape 000289. *** A TAPE ERROR OCCURRED: [No more writable valid tape found].
Normally I will load the proper tapes and run the amflush to push stuff from the holding disk to tapes manually. However this time amflush in this case did not help, Amanda immediately responded with an out of tape error again.
Meanwhile I got some errors from dmesg as well st3: Error 18 (sugg. bt 0x0, driver bt 0x0, host bt 0x0). scsi1 (0,3,0) : reservation conflict
I'm looking for a free backup solution how work in client-server in both environments Linux(server) and Windows(client). in my case, i want to give a disk space quota in my Linux server for each remote windows client.
I need little help on live disk creation and disk image backup.
Can I create live disk using my hard drive installation? If yes then, can I restore the fedora from the live disk to the hard drive. I mean to say that from that live disk can I install fedora again in my hard drive.
Second question is, if I create the disk image of my hard drive( including ntfs & FAT32 partition) , can I restore it in a blank drive. If so , then can os will be restored also?
I'm looking for a simple solution to backup my CentOS Server (5.x) on a daily base to a mounted disk. I found the glastree tool but I have no clue if it will work on CentOS.All recommendations, tipps, hints and maybe scripts are welcome. Unfortunatelly I'm an Linux newbie and starting with Linux CentOS a couple of weeks ago
I want to backup data and upload to online hosting services.Since I'm uploading stuff online, I only want to upload encrypted data (so that even the hostiing service admins cannot look at the data).Thus, I first want to encyrpt my data locally that I want to backup. Since I will be making changes locally to the data, I want some sort of incremental imaging system where the incremental changes are stored in seperate files so that I only have to upload the incremental encrypted changes.
Duplicity is an option, but it uses GPG, which makes it a bit complicated; and I was wondering if there was any alternative which was simpler as I am only doing the encryption and backup locally.
How to backup and restore local folders in K Mail. I understand that this is a rudimentary question-- under K Mail in 11.2 there is no backup and restore option for local folders (that I have been able to find anyway). I use 11.2 on this machine where I do all e mail, browsing and everything pretty much internet related. I am going to upgrade to 11.4 in another week and want to make sure that I understand backup and restore procedures for K Mail...in case something untoward happens during the upgrade to 11.4.

Does anyone know of any decent enterprise level backup solutions for Linux? I need to backup a few servers and a bunch of desktops onto one backup server. Using rsync/tar.gz won't cut it. I need like bi-monthly full HDD backups, and things such as that, with a nice GUI interface to add/remove systems from the backup list. I need basically something similar to CommVault or Veritas. Veritas I've used before but it has its issues, such as leaving 30GB cache files. CommVault, I have no idea how much it is, and if it supports backing up to a hard drive rather than tape.

EDIT:I have only ONE computer on which the data resides, and on which the backup image image is made. That is, I have a directory foo on my computer, the backup of which will be made to back-foo on the same computer. I want back-foo to be in an encypted form Then back-foo will be uploaded (unencrypted) to microsft live storage or to spideroak storage etc. Since back-foo is encrypted, my upload is secure. And since I'm uploading, I want incremental backup support, that is, the backup utility should create new files which contain the incremental changes so that I can upload only the new files which contain the changes.
I made a script to backup file from each host with general password in local network. This script using SSH Pass and Rsync with this
syntax: rsync --rsh="sshpass -p password ssh -l root" hostath destinationpath Everything is okay under 9.10 version until I migrate to Ubuntu 11.04, there is always give an error: rsync error: received SIGINT, SIGTERM, or SIGHUP (code 20) at rsync.c(541) [Receiver=3.0.7]

I installed a new disk and need to share it on NFS, but the share keep failing. I think the reason is the disk was not mounted when NFS started. How do I guarantee local disk mounted before NFS?
I'm using a dell XPS M1530 laptop with windows vista and ubuntu 10.04. Last week when I turned on my laptop I got an error saying internal hard disk not found. When I called dell support, I have been told that my hard disk is dead. I have few important stuffs in my hard disk for which I don't have any back. So I tried using ubuntu live CD to back up my data as in the link below.[URL]..I'm using ubuntu 10.04 live CD(64 bit). When I go to my places after booting from the live CD I can't see any partition showing my hard disk. I can see "Computer". When I go in it I can only see "File System" and nothing related to my partitions in my HDD. What should I do now? Do I need to mount my hard disk or is my HDD completely dead?
I booted my laptop from the FC 13 Live CD.I'd like to mount the local disk while booted from the Live CD.In older versions of Linux, this used to be as simple as "mount /dev/sda2 /mnt/whatever".But, no longer Progress. When I do "fdisk -l /dev/sda", while booted from the FC13 Live CD, the /dev/sda2 partition shows up as "Linux LVM". My question: how can I mount the partition containing home directories from the "Linux LVM" partition?
I installed Ubuntu 10.10 (64 bit) on a Dell Precision 670 desktop that I share with another user. The OS is installed on a 160GB disk, which also has the /home folders. There is also a second internal disk (1TB) which has shared files (music, pictures, etc).
How can I configure Ubuntu such that either person can read or write to this shared disk? Right now, if someone is logged into the PC, the disk can be mounted, but then it is not available to the other person.
I have installed a linux server in my office to run 16 machines. Its main use will be a internal mail server but will be also running websites.
I have installed Ubuntu 9.10 server x64 and have got apache running.
I am looking for the simplest more robust solution for smtp, pop3 and imap. I have only ever used qmail before and found it a pain to configure and its getting old so I though I should probably try something new. I have not much experience with running pop3 or imap on linux so would love a suggestion on that.
