===== Check Versions =====

==== Clients ====

**Web Interface -> Manage Log -> Backup Job**

==== Server ====

**Web Interface -> Manage System -> Software License**

===== Upgrade OBSR =====

Upgrade Guide: https://forum.ahsay.com/viewtopic.php?f=94&t=9775

:!: If you are using RDR, upgrade that first.

:!: If not doing a major version upgrade, see below for patches and hotfixes.

Begin the upgrade:

<file>
# Declare locations
OBS_HOME=/opt/obs; export OBS_HOME
OBS_HOME_BAK=/opt/obs.bak; export OBS_HOME_BAK

# Stop services
/etc/init.d/obsr stop

#Create backup less user data - you should back it up too if you can
tar -czvf /root/obs_backup.tgz --exclude="/opt/obs/user/*" /opt/obs

# Uninstall the old version leaving data and configuration intact
sh $OBS_HOME/bin/uninstall.sh

# Delete old folder if it exists and rename $OBS_HOME to $OBS_HOME_BAK
rm -rf $OBS_HOME_BAK
mv $OBS_HOME $OBS_HOME_BAK
mkdir $OBS_HOME

# Move into $OBS_HOME, download the latest version and extract it
cd $OBS_HOME
wget http://ahsay-dn.ahsay.com/current/obsr-nix.tar.gz
tar -xzvf obsr-nix.tar.gz

# Delete a couple of large log files in order not to fill the root partition
rm -f $OBS_HOME_BAK/logs/catalina.out.*

# Copy original files into the upgrade installation
/bin/cp -avr $OBS_HOME_BAK/conf/*.xml $OBS_HOME/conf/
/bin/cp -avr $OBS_HOME_BAK/logs $OBS_HOME/
mv $OBS_HOME_BAK/user $OBS_HOME/
/bin/cp -avr $OBS_HOME_BAK/system $OBS_HOME/
mv $OBS_HOME_BAK/rps-system $OBS_HOME/
mv $OBS_HOME_BAK/rcvshome $OBS_HOME/

sh $OBS_HOME/bin/install.sh
</file>

Finally, logon to the AhsayOBS Web Management Console and press the **''Update''** button here:

**Manage System -> Software License -> Update**

:!: Note that these upgrade instructions do not include handling customizations such as branding.

:!: Note that AUA must be reenabled after an upgrade.

<file>
vim webapps/obs/liveUpdate/index.xml
</file>

===== Performance =====

  * Use separate disks
    * OS
    * OBS System
    * OBS User Homes
      * Divide users over multiple User Homes
  * Mount filesystems with ''noatime'' option

===== Downloads and Docs =====

===== Move OBS to New Hardware =====

http://pedia.ahsay.com/article.aspx?article=1786&p=16 

===== Do a Centos 6 Minimal Install =====

==== Partitioning ====

During the installation, you might use manual partitioning like:

^Partition^Size^Mountpoint^Filesystem^
|/dev/sda1|200MB|/boot|ext4|
|/dev/sda2|15GB|/|ext4|
|/dev/sda3|2GB|n/a|Swap|
|/dev/sda4|Rest of first disk|/opt/obs/user|ext4|
|/dev/sdb1|All of second disk|/mnt/obs_homes_1|ext4|
|/dev/sdc1|All of third disk|/mnt/obs_homes_2|ext4|

==== Install Latest Updates ====

<file>
yum update -y
reboot
</file>

==== Install Needed Tools ====

<file>
yum -y install wget vim-enhanced ntp acpid
</file>

==== Configure Networking ====

See [[networking:linux:static_ip_addr|Static IP Address]].

Verify the hostname and IP address are set in /etc/sysconfig/network and in /etc/hosts.

==== Configure Timekeeping ====

[[networking:linux:linux_time|Linux Timekeeping]]

<file>
chkconfig ntpd on
service ntpd start
</file>

==== Configure SElinux ====

Set selinux to Permissive mode and set the system to relabel on the next reboot:

<file>
vim /etc/selinux/config

SELINUX=permissive

echo 0 >/selinux/enforce
touch /.autorelabel
sestatus -v
</file>

==== Configure Bash Shell ====

<file>
cat >> ~/.bash_profile << EOF

alias ll='ls -l'
alias la='ls -A'
alias l='ls -CF'
alias ls="BLOCK_SIZE=\'1 ls --color=auto"
alias free="free -m"
export GREP_OPTIONS='--color=auto'
PS1='\[\033[00;36m\]\u\[\033[00m\]@\h:\[\033[05;33m\]\w\[\033[00m\] \$ '
export HISTCONTROL=ignoredups
EOF
</file>

===== Firewall =====

:!: Expose only TCP port 80 and 443 (Ahsay) plus UDP 123 (NTP) to the public.

==== CentOS Firewall ====

The built-in CentOS firewall only allows port 22 (SSH) by default and blocks all other traffic.

<file>
iptables -I INPUT 3 -p udp --dport 123 -j ACCEPT
iptables -I INPUT 3 -p tcp --dport 443 -j ACCEPT
iptables -I INPUT 3 -p tcp --dport 80 -j ACCEPT

/sbin/service iptables save
iptables --line-numbers -nL
</file>

==== Arno's Firewall ====

If your backup server has an interface directly connected to the Internet, you should consider Arno's Firewall.

Disable the built-in firewall:

<file>
service iptables stop
service ip6tables stop
chkconfig iptables off
chkconfig ip6tables off
</file>

**[[networking:firewall:arno_s_firewall|Arno's Firewall]]**

I don't remember what these very important notes were for:

<file>
NAT_LOCAL_REDIRECT=1
NAT_FORWARD_TCP="80>209.104.9.38~9080 443>209.104.9.38~9443"
</file>

===== Install OBS =====

<file>
OBS_HOME=/opt/obs; export OBS_HOME
mkdir $OBS_HOME && cd $OBS_HOME
wget http://ahsay-dn.ahsay.com/current/obsr-nix.tar.gz
tar -xzvf obsr-nix.tar.gz
sh $OBS_HOME/bin/install.sh
</file>

===== First Login =====

Login to the new backup server using a web browser.  Use a fully qualified domain name, an IP address won't work.  That means you must have DNS configured or have a 'hosts' file entry for the FQDN to resolve properly.

The default username/password is **system/system** - change them to 'admin' and your own password:

**Manage System -> Server Configuration -> Login Name** 

===== Filesystem Tweaks =====

Depending on how you partitioned the drive when you installed the OS, you may need to add a new logical volume for OBS to use.  Ideally, the OBS 'homes' will be separate from the host OS so if a disk is filled, the server won't crash.

Assuming the entire installation disk was used as a LVM PV (physical volume), this command will use the rest of it to create a new LV (logical volume) for OBS 'homes':

<file>
lvcreate -n lv_obs_homes -l 100%FREE vg_backup

mkfs.ext3 /dev/vg_backup/lv_obs_homes
</file>

Edit /etc/fstab and add add a line to mount the new LV with the 'noatime' option:

<file>
vi /etc/fstab

/dev/mapper/vg_backup-lv_obs_homes    /mnt/obs_homes       ext3    defaults,noatime    0 0

mkdir /mnt/obs_homes/{system,user}
</file>

**Manage System -> Server Configuration -> System Home**
  * ''/mnt/obs_homes/system''
**Manage System -> Server Configuration -> User Homes**
  * ''/mnt/obs_homes/user''

===== Copy Data =====

<file>
rsync -av /usr/local/obs/system root@192.168.1.6:/opt/obs/

rsync -av /usr/local/obs/user root@192.168.1.6:/opt/obs/
</file>

===== Add Additional Storage =====

https://help.ahsay.com/display/2/kb/article.aspx?aid=2437&n=1&docid=67930

Install a new disk drive, then create one large GPT partition and format it:

<file>
echo ';' | sfdisk /dev/sdx

mkfs.ext3 /dev/sdx1
</file>

You want to mount the new space using the disk's UUID as a best practice.  Run this command after the format has finished to determine the UUID:

<file>
blkid
</file>

Edit /etc/fstab to mount the new partition with the 'noatime' option.

<file>
vi /etc/fstab

# additional storage for OBS
/dev/mapper/vg_backup-lv_obs_homes           /mnt/obs_homes         ext3    defaults,noatime    0 0
UUID=40a09cc6-47d7-4061-b93b-a30d45659075    /mnt/obs_homes_2       ext3    defaults,noatime    0 0
UUID=299dc4c1-0652-47d3-bbe5-bcf1788647d0    /mnt/obs_homes_3       ext3    defaults,noatime    0 0

mount -a
mount
</file>

Then you can assign the new space for user homes in the web interface:

Manage System -> Server Configuration -> User Homes
  * ''/mnt/obs_homes_2''
  * ''/mnt/obs_homes_3''

===== Data Validation =====

http://forum.ahsay.com/viewtopic.php?t=5746

===== Configuration Archival =====

http://www.ahsay.com/jsp/en/home/index.jsp?kw=&pageContentKey=ahsay_products_ahsayobs_features_configuration-archival

**Manage System -> Routine Job -> Configuration Archival**

The Configuration Archival feature is designed to faciliate a quick and simple recovery of an AhsayOBS server after an outage so as to minimize the down time of backup service.

With this feature enabled, a copy of AhsayOBS configuration settings will be backed up to Ahsay™ License Server everyday so that when a disaster strikes, the backup server administrator is able to download the backed up AhsayOBS configurations from the Ahsay™ License Server and restore them quickly onto a new AhsayOBS machine.
