View 2 Replies View RelatedUbuntu Servers :: Remote Backup Ftp Server With Confidential Data?
Feb 15, 2011I already have an ubuntu backup server in my location and need this one server to be backed up remotely in another state. this other location is a helpdesk so there's a danger that they can gain access to confidential data. I'll be setting up this new server as an ftp server but need to set the ftp folder to only allow access to the backup server and me. Because its remote on the helpdesk side, they'll need some access to the file system but need to be completely blocked off from the ftp folder where all the data is at. How can I make sure I can keep them away from my data and still be able to retrieve or copy files over without permission issues between both servers?

Dec 23, 2010I'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:

It works, but then I get these issues:

I can reset the UUID, but it's difficult to have to do this every day.
Ubuntu Servers :: Backup Script To Check If A Path Is Mounted?
Mar 6, 2011I'm writing a script to rsync some directories to external hdd for backup.
My external hdd gets automatically mounted to /media/backup1
My script then backs up predefined directories to /media/backup1.
I have added this script to cron to run once every day.
The problem is that in the case where the drive is not plugged in and the script runs, it backs up to my local hard drive, and since it is more than 70% full, it fills it up by duplicating that 70% onto itself.
I have taken the script further, to test whether /media/backup1 is mounted. If it is, the backup will run. If it is not, it will bail out.
I'm using the mountpoint program to test for mounts.
My script so far:
Code:
#!/bin/bash
if [[ `mountpoint /media/backup1` ]]; then
echo "filesystem mounted"
# The backup function. Commented out for testing.
[Code]....

Software :: Backup A Few Servers And A Bunch Of Desktops Onto One Backup Server?
May 10, 2010Does 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.

Apr 6, 2011I have 2 servers. One is an operational CentOS + cPanel server and the other is a blank CentOS server. I want to use cPanel's backup suite to backup our customers accounts but I want to do it so the blank server is mounted to the cPanel server, rather than an FTP backup. If that makes sense. I believe from previous experience that NFS is the way to go but I'm not sure.

May 13, 2011Here is my brief hardware and software detail in my production environment : AMD Phenom X4 3.4gHZ (Over clock to 4gHZ, 8G of Memory, 1TB 7200rpm Harddrive, Running Ubuntu server 10.10.My web production environment were pieced together 3 weeks ago.Here is my dilemma. started out with less that 40 users and now hitting 4,000 unique users per day.Now I am thinking I need faster write to disk and backup of data so I am thinking about putting together a Raid5.

Debian :: Encrypted Backup To Remote Dumb Server
Mar 23, 2011This is not a regular backup. I only want to backup selective directories so personal files (photographs, documents, sourcecode) will be kept safe in case of a total system meltdown. This'll be 15GB max. Basically the digital variant of a fire resistant safe. I looked into duplicity but that requires me to install gpg keys on the target machine, which I can not do. I rather have a solution that just relies on just a working shell account and diskspace on the target server.
I thought of writing a simple script to do the following:
1. Mount remote server with sshfs
2. Mount encrypted container at remote server (LUKS, TrueCrypt?)
3. Loop over predefined directories on local machine and copy to encrypted container (rdiff-backup?)
Based on these requirements:
- Target server is "dumb": only ssh access + diskspace (i.e. no installing of gpg keys)
- Encrypted container should grow/shrink to fit contents
- Encrypted container should be easily decryptable on any OS if you have the password
- Once data leaves client server it should be encrypted: sysadmin on target server should never be able to see unencrypted data.
Server :: Backup Goes To Local Disk?
Jun 7, 2011I 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?

Server :: Creating Backup Disk Image Of RAID 1 Array (MDADM)?
Oct 27, 2010We 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.

Server :: Amanda Unable To Copy Backup File From Holding Disk To Tapes

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.

View 1 Replies View RelatedUbuntu Servers :: FTP From Server To Remote File Server?
Jul 6, 2010I support a small business which runs a headless Ubuntu Server (10.04 32bit) as a file server which is accessed by Windows machines.Although the company has it's own back-up procedure they have decided to back-up some (none sensitive) files online. The have chosen FileFactory (http://www.filefactory.com/) as the host for this. FileFactory allows files to be uploaded to their server by FTP however I do not know how to set this up on the server.
The idea, if it is possible, is to connect to FileFactory through FTP and then synchronise the data using an Rsync command.I normally access the server through Webmin and it has vsFTP installed. I can access the company's server by FTP from inside and outside of the network so I know that vsFTP is working for incomming connections however I cannot work out how to configure it to connect to the FileFactory server.

View 7 Replies View RelatedServer :: Production Servers HD Backup
Feb 24, 2010I administer several web hosting (combined with mail relays and other services) production servers under Debian GNU/Linux. I began giving these public services two years ago via three boxes: the first is a gateway which controls traffic via iptables (it's attached to a DSL modem) between a public subnet (the DMZ) and a local network which connects several workstations. In the DMZ subnet I maintain two Pentium-III era boxes, they've grown in services since I set them up. Actually, I think I should buy new ones, but, you know, I want to save money and lenghten its life.
So, they've grown in data hosted, but I've never implemented a resilent backup system. I've set up some rsync tasks sheduled via cron jobs to copy the entire UNIX file system in each of the DMZ boxes, but I'd like to be prepared before an unexpected "real" crash of some HDD, I mean, some problem that renders a disk unusable.
AFAIK, sysadmins sync entire HD backups which are capable of recovering a system via swapping the unusable unit with the backup unit. Maybe the best fashion is to implement a RAID mirroring the unit, I'm I right? So, keeping my systems as they are, I mean, capable of using 4 parallel ATA units, what would you do? Use dump, rsync or some other way to have an operational second unit with an exact copy in a bootable second drive, in order to quickly swap it if the main unit fails?
Comes to my mind to partition a second unit (so making it bootable) and backup daily via rsync only those parts of the unix file system hierarchy which are necessary to boot a system properly. What do you think about this workaround?
Ubuntu Servers :: Tunnel To Remote NFS Server?
Jan 11, 2011Does anyone know the best and simplest way to do this?

Lots of the information I have been reading is not up to date it seems. Does anyone have any experience with this?
View 1 Replies View RelatedUbuntu Servers :: Setting Up Home Server With Backup Imaging For Clients?
Jan 31, 2010I'm trying to setup a server at home, it has some practical implications, but largely it is just to take a stab at it. But I need the help of someone with more experience than I in defining exactly what I'm looking to do.
Here's what I have: old PC running Gutsy server connected to router. Several laptops at home connected via wifi to router. All laptops running either Windows or Ubuntu. Here's what I'm looking for: The server centralizes file storage for all clients. I would likely incorporate a RAID and some synchronised imaging of the files. I also want the server to create disk images of the clients hdd, regardless of client OS.There would also be some shares that would be publicly accessible (myself and friends accross the country would be able to access the same drive).
So I was thinking something like what corporate environment would be nice, you log into a profile that exists on the server. Like a dumb client...all data would be stored on the server. But I'm thinking that's more like a network boot and wouldn't work via wifi (or would it?). Also that wouldn't lend itself well to laptops used on the road in areas without net access. now I'm thinking each client would have its own locally installed OS, and they would just access networked shares. I could store sensitive files on the shares, but that wouldn't provide complete backup solution for each client.
Without rambling on anymore, anyone care to throw out some ideas? I'm really just looking to see if I can do what I want. The focus is on centrallizing files, securley backing up data and client OS's and ability to restore said images quickly.
Ubuntu Servers :: Mysql-admin Won't Schedule Backup But Will Manual Backup

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:

It seems that MySQL can open and write to the file fine, it just can't dump
Ubuntu :: Backup Snapshots Show Up On The Desktop As Mounted Files?
Jan 20, 2011I am using Ubuntu 10.04 x86_64. I log in to the machine using nfs. For a problem with mounting my home directory, I had to copy all the contents of my home directory (including all configuration files) from a recent snapshot on to itself. That is, I did something like,
Code:
cp -r /home/user/user /home/user
All of my recent data and program configurations were in /home/user/user. So after the copy operation, I logged out and logged back in again to see that all my configuration and data was restored to what I wanted. But the problem is that now on my desktop I see hundreds of mounted volumes. These are coming from an hourly/weekly snapshot program. The tech support guys for my lab have suggested copying all relevant data to a backup and then deleting the home directory altogether. But I don't want to configure all programs all over again. I think I should be able to get rid of the problem by editing/deleting one or more desktop configuration files. I just don't know which ones. I tried looking around the gconf-editor but was overwhelmed at the amount of information on there.

I can issue the command but the machine remains on. I also cannot get to the desktop via VNC.The reason for this, is that there is no monitor attached so Ubuntu says that it is trying to run in Low Graphics Mode. I found this out as I plugged the monitor in to my server.So question is, how do I get around this? How can I set up Ubuntu to get past this, or do I need to install Ubuntu Server?
