.. DISCLAIMER
16+
-------------------------
17+
I take no resposibility for any data loss or corruption when using this script.
18+
This script will not help in the event of a hard drive crash. If a copy of the
19+
backup has not been stored offline or on another PC. You should copy your backups
20+
offline regularly for best protection.
21+
22+
Happy backing up...
23+
24+
25+
26+
.. INSTALL
27+
-------------------------
28+
Extract the package into a directory. If you are reading this you have probably done
29+
this already.
30+
31+
To install the Automysqlbackup the easy way.
32+
1. Run the install.sh script.
33+
2. Edit the /etc/automysqlbackup/myserver.conf file to customise your settings.
34+
3. See usage section.
35+
36+
To install it manually (the hard way).
37+
1. Create the /etc/automysqlbackup directory.
38+
2. Copy in the automysqlbackup.conf file.
39+
3. Copy the automysqlbackup file to /usr/local/bin and make executable.
40+
4. cp /etc/automysqlbackup/automysqlbackup.conf /etc/automysqlbackup/myserver.conf
41+
5. Edit the /etc/automysqlbackup/myserver.conf file to customise your settings.
42+
6. See usage section.
43+
44+
45+
46+
.. USAGE
47+
-------------------------
48+
49+
Automysqlbackup can be run a number of ways, you can choose which is best for you.
50+
51+
1. Create a script as below called runmysqlbackup using the lines below:
52+
53+
#~~~~ Copy From Below Here ~~~~
54+
#!/bin/sh
55+
56+
/usr/local/bin/automysqlbackup /etc/automysqlbackup/myserver.conf
57+
58+
chown root.root /var/backup/db* -R
59+
find /var/backup/db* -type f -exec chmod 400 {} \;
60+
find /var/backup/db* -type d -exec chmod 700 {} \;
61+
62+
#~~~~~ Copy To Above Here ~~~~
63+
64+
2. Save it to a suitable location or copy it to your /etc/cron.daily folder.
65+
66+
3. Make it executable, i.e. chmod +x /etc/cron.daily/runmysqlbackup.
67+
68+
69+
The backup can be run from the command line simply by running the following command.
70+
71+
automysqlbackup /etc/automysqlbackup/myserver.conf
72+
73+
If you don't supply an argument for automysqlbackup, the default configuration
74+
in the program automysqlbackup will be used unless a global file
75+
76+
CONFIG_configfile="/etc/automysqlbackup/automysqlbackup.conf"
77+
78+
exists.
79+
80+
You can just copy the supplied automysqlbackup.conf as many times as you want
81+
and use for separate configurations, i.e. for example different mysql servers.
82+
83+
!!! NEW !!!
84+
----------
85+
As of version 3.0 we have added differential backups using the program diff. In an
86+
effort to make the reconstruction of the full archives more user friendly, we
87+
added new functionality to the script. Therefore, while preserving the old syntax,
88+
we created options for the script, so that the new functions can be accessed.
89+
90+
Usage automysqlbackup options -cblh
91+
-c CONFIG_FILE Specify optional config file.
92+
-b Use backup method.
93+
-l List manifest entries.
94+
-h Show this help.
95+
96+
If you use these options, you have to specify everything according to them and can't
97+
mix the old syntax with the new one. Example:
98+
99+
before (still valid!):
100+
101+
>> automysqlbackup "myconfig.conf"
102+
103+
now:
104+
105+
>> automysqlbackup -c "myconfig.conf" -b
106+
107+
which is equivalent to
108+
109+
>> automysqlbackup -bc "myconfig.conf"
110+
111+
or in English: The order of the options doesn't matter, however those options expecting
112+
arguments, have to be placed right before the argument (as seen above).
113+
114+
The option '-l' (List manifest entries) finds all Manifest files in your configuration
115+
directory (you need to specify your optional config file - otherwise a fallback will be
116+
used: global config file -> program internal default options). It then filters from which
117+
databases these are and presents you with a list (you can select more than one!) of them.
118+
Once you have chosen, you will be given a list of Manifest files, from which you choose
119+
again and after that from which you choose differential files. When you have completed
120+
all your selections, a list of selected differential files will be shown. You may then
121+
choose what you want to be done with/to those files. At the moment the options are:
122+
- create full backup out of differential one
123+
- remove the differential backup and its Manifest entry.
124+
125+
126+
.. CONFIGURATION OPTIONS
127+
-------------------------
128+
129+
!! "automysqlbackup" program contains a default configuration that should not be changed:
130+
131+
The global config file which overwrites the default configuration is located here
132+
"/etc/automysqlbackup/automysqlbackup.conf" by default.
133+
134+
Please take a look at the supplied "automysqlbackup.conf" for information about the configuration options.
135+
136+
Default configuration
137+
CONFIG_configfile="/etc/automysqlbackup/automysqlbackup.conf"
138+
CONFIG_backup_dir='/var/backup/db'
139+
CONFIG_do_monthly="01"
140+
CONFIG_do_weekly="5"
141+
CONFIG_rotation_daily=6
142+
CONFIG_rotation_weekly=35
143+
CONFIG_rotation_monthly=150
144+
CONFIG_mysql_dump_usessl='yes'
145+
CONFIG_mysql_dump_username='root'
146+
CONFIG_mysql_dump_password=''
147+
CONFIG_mysql_dump_host='localhost'
148+
CONFIG_mysql_dump_socket=''
149+
CONFIG_mysql_dump_create_database='no'
150+
CONFIG_mysql_dump_use_separate_dirs='yes'
151+
CONFIG_mysql_dump_compression='gzip'
152+
CONFIG_mysql_dump_commcomp='no'
153+
CONFIG_mysql_dump_latest='no'
154+
CONFIG_mysql_dump_max_allowed_packet=''
155+
CONFIG_db_names=()
156+
CONFIG_db_month_names=()
157+
CONFIG_db_exclude=( 'information_schema' )
158+
CONFIG_mailcontent='log'
159+
CONFIG_mail_maxattsize=4000
160+
CONFIG_mail_address='root'
161+
CONFIG_encrypt='no'
162+
CONFIG_encrypt_password='password0123'
163+
164+
!! automysqlbackup (the shell program) accepts one parameter, the filename of a configuration file. The entries in there will supersede all others.
165+
166+
Please take a look at the supplied "automysqlbackup.conf" for information about the configuration options.
167+
168+
169+
170+
.. ENCRYPTION
171+
-------------------------
172+
173+
To decrypt run (replace bz2 with gz if using gzip):
174+
175+
openssl enc -aes-256-cbc -d -in encrypted_file_name(ex: *.enc.bz2) -out outputfilename.bz2 -pass pass:PASSWORD-USED-TO-ENCRYPT
176+
177+
178+
179+
.. BACKUP ROTATION
180+
-------------------------
181+
182+
Daily Backups are rotated weekly.
183+
Weekly Backups are run on fridays, unless otherwise specified via CONFIG_do_weekly.
184+
Weekly Backups are rotated on a 5 week cycle, unless otherwise specified via CONFIG_rotation_weekly.
185+
Monthly Backups are run on the 1st of the month, unless otherwise specified via CONFIG_do_monthly.
186+
Monthly Backups are rotated on a 5 month cycle, unless otherwise specified via CONFIG_rotation_monthly.
187+
188+
Suggestion: It may be a good idea to copy monthly backups offline or to another server.
189+
190+
191+
192+
.. RESTORING
193+
-------------------------
194+
195+
Firstly you will need to uncompress the backup file and decrypt it if encryption was used (see encryption section).
196+
197+
eg.
198+
gunzip file.gz (or bunzip2 file.bz2)
199+
200+
Next you will need to use the mysql client to restore the DB from the sql file.
201+
202+
eg.
203+
mysql --user=username --pass=password --host=dbserver database < /path/file.sql
204+
or
205+
mysql --user=username --pass=password --host=dbserver -e "source /path/file.sql" database
206+
207+
NOTE: Make sure you use "<" and not ">" in the above command because you are piping the file.sql to mysql and not the other way around.
