Server :: Red Hat 5.5 - Amanda (or Alternative) Backup
Jun 6, 2010
I'm fairly competent with Linux at this stage and as we have just installed a new Red Hat 5.5 Server to host our DB at work it has basically fallen to me to sort everything out. The only thing I'm not 100% on is a backup strategy at the moment. Basically, the server / DB is not that big and as such we will be doing a full backup every night of the whole file system.
As it is there are several LVM partitions across several disks (these are all virtual both on the SAN and as a virtual machine). My question is what would be the best way to create a full backup overnight of the whole server including all the partitions (or a backup of each partition I'm guessing is more feasible). This doesn't seem to be too difficult to do, but my main problem is restoring the backup.
Is it a simple matter of basically .tar'ing the whole / filesystem? and if so, to restore can I just use a live CD to restore the partition that is needed? How does LVM affect the restoration process? I have looked at Amanda as a backup solution, though we wont be backing up directly to tape (backup to a share location then copy to the tape drive).

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).

After my 8.04 debacle here:I basically gave up on trying to write an install guide for Hardy and Amanda. Others had done it better and with how muddled I was by the end of getting a working server, I wasn't sure I could repeat it.Now in Lucid, I've managed to get another working amanda server going, I'm fairly sure I can repeat it and but I question:Installation with 'apt-get install amanda-server' uses the user backup in the group backup.Installation of the ZWC client uses the user amandabackup. while thankfully ZWC has included reg keys:
HKEY_LOCAL_MACHINESOFTWAREmandaWC1.0Install BackupUserHKEY_LOCAL_MACHINESOFTWAREmandaWC1.0Install RecoveryUserto change the user on the client, this is messy, requires regedit (which normally is locked out by group policy), editing the service in service.msc and creation of a new user account named backup in addition to the installer's default on each client.The actual question is:1) Is there a reason for the use of backup:backup? (rather than amandabackup:disk or amandabackup:backup)
2) Is there any sort of flag that could be set, script to change the user within the repo atinstall time.Or generally an easier way of doing this than compiling each time I do an install.

I installed amanda on a client that uses Red Hat Enterprise Linux 4. When I do an amcheck from the server, I get this:
Amanda Backup Client Hosts Check
--------------------------------
WARNING: 192.168.3.23: selfcheck request failed: recv error: Connection reset by peer
Client check: 1 host checked in 0.022 seconds. 1 problem found.
I am using bsdtcp. I get an ACK error if I switch the client to bsd authentication. I read that I should enter servers adress to hosts file in /etc/ directory?

I want to backup data and upload to online hosting services. 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.
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 did a port scan on my server from outside my network and saw that port 10080 AMANDA is open.Amanda isn't installed on any of my computers or my server and the port is not forwarded by my modem or router. So why is this port open and how can I close it?

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.

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.

After several hours of searching web I give up. Problem: I want to run mysqld with datadir option.When I run it manually without --datadir everything is fine I have added required lines to /etc/apparmor.d/usr.sbin.mysqld and restarted apparmor
Quote:
/sys/devices/system/cpu/ r,
/disk0/mysql r,
/disk0/mysql/** rwk,
Then I copy /var/lib/mysql to my location, carefully, 10 times checking all the permissions and run. But daemon exits immediately after running.

At my work we have a windows 2008 that serves as a "bounce pc" i cant find any better word (thats directly translated from the word we use in my language) What i mean by that is that if we want to access the server net and so on we first have to rdp to a w2k8 computer and from their ssh/rdp/www futher to admin. The few admin have their own account and can be logged on at the same time, also with the rdp client you can mount your local c: witch can be very useful when you need to transfer file to the servers (they don't have access to the Internet). Now im looking for a similar service but for linux, suggestions?
The client that you connect with should be available to as many platforms as possible?

I currently have a server running Windows Home Server and was wanting to know if Ubuntu Server could do the following requirements I currently enjoy
1. Media Streaming, to multiple devices simultaniously i.e. pc/xbob360/PS3 all at the same time. Possibly re-encoding OTF.
2. Remote Access, not just to the server but linking(so i can rdp to my main rig through the server from any internet location) to other systems on the "Home" Network both Linux and Windows.
3. Drive Pooling with redundancy, I want to be able to add and remove HDD and just have it expand the pool so current folders can just grow, but also have it duplicate or make redundant copies so if a HDD fails it can still be recovered.
4. Backup of machines on the network, either manual or scheduled, of both Linux and Windows machines
5. App sharing would be a plus but not required, so I could run a Linux app from the server seamlessly on my windows pc.
6. Basic file storage and browsable structure from windows machines.
I realise this may be a tall order and I don't expect it to be easy or straight forward in any way, but I really hate WHS, it has the slowest file access speed of any os i have ever seen, and is so buggy its unbelievable.

I've run into a problem when trying to restore a file using AMANDA.My setup is as follows:
I have a server that runs on Red Hat Enterprise Linux Server release 5.4 and I have a client that runs on Red Hat Enterprise Linux AS release 4. I successfully backed up files on the client using AMANDA.Now I am trying to restore a file from the backup and restore it to the client running Red Hat Enterprise Linux AS release 4. In order to do this, I have to go through the server which runs Red Hat Enterprise Linux Server release 5.4.
Here is the problem I encounter. When I try the restore, it freezes at the extraction process. I've left it running for the night and still it is stuck at the same place. The restore never completes.So I'm wondering if anyone knows what seems to be the issue? Could it be that the AMANDA driver I installed does not allow restore with different versions of Red Hat? Or is there an update in Red Hat 4 that would fix this issue?

I'm configuring Amanda Enterprise on an OpenSuSE 11.3 system, and everything but the scheduled backups are running. I decided to try and fix it tonight, but I'm pretty fed up by now.
So here's the background:
The application creates an account on the box named "amandabackup" and adds it to the 'video' and 'disk' groups.
It generates cron jobs in /etc/zmanda/zmc_aee/crontab, which is configured as the location of the crontab file for the amandabackup user.
The crontab is owned by amandabackup:disk with a mask of 644.
So I played around with it a little bit; I ran the backup task manually as amandabackup, which worked fine.
I then tried adding the following to the crontab:
And touched amandacron.log, then made sure it was owned by amandabackup with a mask of 644 (i also tried /etc/amanda/amandacron.log, which is a directory the account stores backup session configs in, so I know it can write to it properly). The file is never updated. I tried adding amandabackup to different groups (it's currently been added to the "Users" group), with no success. I tried a symlink to the crontab file in /etc/cron.d to see if that would make a difference, but it didn't.
At this point, I went online and tried some more stuff I found:
I checked /var/log/mail/amandabackup - everything *but* cron jobs were reporting to it.
I verified cron was running with both "ps -ef | grep cron" and "rccron status"
I ensured /var/spool/cron/tabs/amandabackup existed, showed the proper entries, and was set to 644. (this one's the important bit)I checked /var/log/messages, and every minute on the dot I see: <timestamp> /usr/sbin/cron[PID]: Permission Denied
I ensured there was no /etc/cron.allow, and that /etc/cron.deny did not contain amandabackup.
I tried making an /etc/cron.allow, adding amandabackup, and restarting the cron daemon, but this did nothing.
I don't think I've forgotten anything, but my attempts have been getting progressively more feverish, so I'm not positive. Is there some annoying YAST cron panel I'm not seeing? Is there some way of getting more verbose logging out of the cron daemon than just "permission denied"? Is there some draconian rule about crontabs only working based on some otherwise-arbitrary account setting?

I have looked many places for good tutorial on configuration of amanda client with Karmic, but none of them are good enough. I basically got following message no matter what I change in Client side.
1. I am using 64-bit Ubuntu Karmic client with 2.5.2p1 amanda-client with xinetd.
2. The user is backup, group is backup.
3. The config file is located at /etc/amandahosts, and /var/backups/.amandahosts and /var/lib/amanda/.amand ahosts using soft link to the /etc/amandahosts file.
4. /etc/amandahosts file have following line.192.168.0.14 backup amdump.The 192.168.0.14 is server IP address.

I'm trying to install Amanda 3.2 on Ubuntu 10.10 (Maverick) using Ubuntu 10.04 deb package. The installation was successful using the dpkg command. The problem crops up when configuring such amanda. When creating a user amandabackup using passwd amandabackup and then enter in it through su - amandabackup a permission denied problem comes up. When enter amserverconfig Dailyset 1 etc etc the server response with :
amservingconfig: critical (fatal): Cannot create debug file "/var/log/amanda/server/amserverconfig.2010120307947.debug": Permission denied and continues
The permissions are set to rw 1 amandabackup backup. I can't understand why it's telling me permission denied each time.

I have a client that is using a windows based backup system called Retrospect and will be installing Linux to replace his windows server. Right now the way it works is on the XP pro workstation Norton 360 makes a backup to the server and then Retrospect make it backups every night. I want to add a linux based backup system that will give them a historical backup system that had XP pro client software that can backup open files and such I can do away with the Norton backup stuff and streamline this setup. I need it to have the capability to go back in time to restore something of an older date this historical. I was looking into:

I have never used either one and was wondering what the linux community wold recommend between the two or if there is something better that has client software and free and does it have a GUI for my clients? I am leaning toward AMANDA after reading Jeremy's article:

and there seams to be a webadmin gui as well.
