===Description===

The main purpose of this affa package is to make a SME Server a dedicated backup box in a few minutes. Affa backs up as many SME servers as you like or any other servers which have sshd running and rsync installed. Once it is configured, Affa runs reliably unattended and sends warning messages in case of any errors.

'''Note:''' This document also refers to the Affa Version 2 which is not maintained anymore. Information on Affa 3 will be gradually added here once it has been more tested.

==== Affa features at a glance ====

====Affa features at a glance====

−

* Affa is secure: All transfers and connections are made by using the ssh protocol with public/private key authentication

−

* Periodically runs unattended full backups. Only differences to the previous full backup are transferred over the network

−

* Using rsync with optional bandwidth limit and compression allows backups over the internet

−

* Uses hardlink technique, i.e. physical disk space only needed for the differences between two full backups

−

* Keeps a configurable number of scheduled, daily, weekly, monthly and yearly full backup archives

−

* The archives are browseable. No need to unpack them first.

−

* Archives can be mapped to a Samba share.

−

* Backup jobs are started by the cron daemon

−

* Interrupted jobs continuing with already transfered data when restarted

−

* Backups the default e-smith directories and files, when property SMEServer is set to yes

−

* Additional directories and files can be included

−

* Directories and files can be excluded from the backup

−

* Non-SME server linux systems can be backed up by setting the SMEServer property to no and using an include list

−

* In ESXi mode, running virtual machines can be backed up. See [[Backup of ESXi Virtual Machines using Affa]]

−

* Configurable nice level for rsync processes on the backup and source server

−

* Optional run of custom programs before and after a job run (e.g. running tape backup)

−

* Checks the disk space left after a job run with warning levels strict, normal or risky

−

* Extensive checking of failure conditions

−

* Sends failure messages to a configurable list of email addresses

−

* Sends a warning message, if the backup server runs out of disk space

−

* Installs an optional watchdog on the source server in case the backupserver fails (SME Server only)

−

* Watchdog sends warning, if an expected backup did not run (SME Server only)

−

* Watchdog sends a daily reminder message, if the error continues unchecked (SME Server only)

−

* Option to display current status of all jobs showing times of last and next run, size and disk usage

−

* Status can be mailed on a daily, weekly or monthly schedule

−

* Option to display all existing archives of a job shown date, number of files, size and bytes tranferred from the source

−

* Option to send (and revoke) the public key to the source server (SME Server and ESXi only)

−

* Option to rise the backup server to a production server from a backup (SME Server only)

−

* The rise feature does not physically move data and therefore is extremly fast and needs (almost) no extra disk space

−

* Rise option can be run remotely as the NIC driver configuration of the backup server are preserved

−

* Compares installed RPMs on source with backup server. Sends warning message, if not in sync

−

* Undo rise option to restore the backup server

−

* Configurable via a e-smith style db, with one record for each job and a default record for all jobs

−

* Logs to /var/log/affa/JOB.log and /var/log/affa/affa.log with optional debug switch for higher verbosity

−

* Log files are rotated weekly, with 5 logs kept

~~You have a SME 7 production server with hostname 'prodbox‘ and IP 10.200.48.1. ~~

−

~~Set up a second SME 7 box as your backupserver with hostname 'affabox‘ and IP 10.200.48.2.~~

−

~~<ol><li>log into the 'affabox' and install the packages as described above.~~

−

~~</li><li>copy the config helper script sample~~

−

~~cp /usr/lib/affa/jobconfig-sample.pl /root/prodbox-job.pl~~

−

~~</li><li>edit /root/prodbox~~-~~job.pl and set~~

−

~~my $jobname~~=~~'prodbox'~~;

−

~~and~~

−

~~'remoteHostName‘=>'10.200.48.1',~~

−

~~optionally, if the remote server port is configured to e.g. 2222 then set~~

−

~~'sshPort'=>2222,~~

~~/root/prodbox-job.pl~~

−

~~</li~~>~~<li>generate the DSA keys and send the public key to the 'prodbox'~~

−

{{~~Note~~ box|~~When initially doing this step, you will need to temporarily enable "Allow secure shell access using standard passwords" on the production server}}~~

−

~~==== Configuration ====~~

−

~~The configuration is stored in an e-smith style database~~. ~~Use the db command to configure Affa.~~

−

~~The jobname is the record key with the type 'job'. To setup a new job with the name 'prodbox' enter:~~

−

~~db affa set prodbox job~~

−

~~then set the properties~~

−

~~db affa setprop prodbox remoteHostName 192.168.1.1~~

−

~~db affa setprop prodbox TimeSchedule '0030,0730,1130,1330,1730,2030'~~

−

~~db affa setprop prodbox Description 'My Production Server'~~

−

~~db affa setprop prodbox status enabled~~

−

~~and so on...~~

−

~~Alternatively you can you use a script as described above in the 'Quick start' chapter.~~

−

~~To verify your work, type:~~

−

~~db affa show prodbox~~

−

~~Finally set up the cronjobs:~~

−

~~affa --make-cronjobs~~

{{Warning box|This will almost certainly break both your old backups and your new server. ONLY use this in a test scenario until it is fully released}}

{{Warning box|Do not use the ANY Koozali SME v9 affa versions with v10. It will probably break both your backups and your new server}}

Line 228: Line 133:

{{Warning box| Note that on SME9, a new SSH [https://wiki.contribs.org/AutoBlock AutoBlock] feature interferes with the Affa requirement for regular SSH logins! You might have to disable this feature to allow Affa to operate correctly. }}

=== Creation of backup jobs ===

===Creation of backup jobs===

Job configurations of Affa 3 are no longer stored in an e-smith style database. They are stored in configuration files located in ''/etc/affa'' . Create your configuration files in this directory, e.g.

touch /etc/affa/backup-smeserver.conf

where ''backup-smeserver'' is your jobname, and add content as described below.

==== Quick start example ====

====Quick start example====

You have a SME production server with hostname 'smeserver‘ and IP 192.168.0.2.

You have a second SME box as your backup server with hostname 'affabox‘ and IP 192.168.0.10.

Line 295: Line 200:

From here you are able to work as with Affa 2. Modify your config file as required and described below. Automate the backup using the command ''affa --make-cronjobs'', see below.

scheduled.0 and daily.0 or scheduled.0 and scheduled.1. Consider this scenario: A user has renamed directories or files. Rsync sees those as new ones and copies them. Deduplication finds the identical copies in the previous archive and replace them by hardlinks. To use deduplication the Freedup program needs to be installed. Affa actually runs freedup -upg scheduled.0 <previous_archive>.

====Two production servers backup each other====

You have two sites connnected via a VPN and a SME Server running on each site. In that case you don't need a dedicated Affa backup server. Both production servers can additionally act as Affa backup servers backing up the server of the other site. Simply install Affa and configure a job that backs up the other one. You can use all Affa features except of the rise feature.

Line 966: Line 887:

Please pay attention, that you do not backup the archives back to the other site. Set the RootDir property to a path which is not included in the SME default backup list. When leaving the RootDir property to its default '/var/affa', this is guaranteed.

===== Limitations =====

=====Limitations=====

With this kind of setup you cannot use the affa rise feature, as it requires the backup archive to be located on the '''same fileystem''' as the server installation. The rise option uses hardlinks, which are not working across filesystems.

−

===== Automount =====

=====Automount=====

Having the backup archives in the same filesystem is always a risk, which can be minimized by using the automount feature. Then the external filesystem is only mounted during a job run.

Line 1,042: Line 983:

To access the archive directory, you need to mount it manually.

−

==== Copying a AFFA USB hard drive archive to a new disk ====

====Copying a AFFA USB hard drive archive to a new disk====

Affa uses copious amounts of hard links to compress and preserve disk space for its backups. If you are in the situation where you want to copy such a disk archive to a new (bigger) disk, you need to ensure that the hard links are copied correctly or the destination copy may became significantly bigger than the total of the source archive.

One way to copy across file systems (i.e. two different USB disks) and preserve the hard links is as follows:

−

* mount both USB drives but with different mount points. e.g. /media/backup1 & /media/backup2 and then:

*mount both USB drives but with different mount points. e.g. /media/backup1 & /media/backup2 and then:

*In the /var/log/affa/''jobname''.log file you will this message: "SSH connection to ''prodserver ip'' failed. Did you send the public key".

*Resending the keys does not solve the problem.

'''Solution:'''

−

* This is probably due to the key for prodserver that is stored on the affaserver no longer matches the key of prodserver.

−

* You need remove the existing key so that the next ssh connection re-gets the keys from prodserver.

−

* From the command line edit the /root/.ssh/known_hosts file and remove the line for prodserver. It starts with: ''prodserver ip'' ssh-rsa
