MAILCONTENT="stdout" # Set the maximum allowed email size in k. (4000 = approx 5MB email [see docs]) MAXATTSIZE="4000" # Email Address to send mail to? (user@domain.com) MAILADDR="user@domain.com" # ============================================================ # === ADVANCED OPTIONS ( Read the doc's below for details )=== #============================================================= # List of DBBNAMES for Monthly Backups. MDBNAMES="mysql $DBNAMES" # List of DBNAMES to EXLUCDE if DBNAMES are set to all (must be in " quotes) DBEXCLUDE="" # Include CREATE DATABASE in backup? CREATE_DATABASE=yes # Separate backup directory and file for each DB? (yes or no) SEPDIR=yes # Which day do you want weekly backups? (1 to 7 where 1 is Monday) DOWEEKLY=6 # Choose Compression type. (gzip or bzip2) COMP=gzip # Compress communications between backup server and MySQL server? COMMCOMP=no # Additionally keep a copy of the most recent backup in a seperate directory. LATEST=no # The maximum size of the buffer for client/server communication. e.g. 16MB (maximum is 1GB) MAX_ALLOWED_PACKET= # For connections to localhost. Sometimes the Unix socket file must be specified. SOCKET= # Command to run before backups (uncomment to use) #PREBACKUP="/etc/mysql-backup-pre" # Command run after backups (uncomment to use) #POSTBACKUP="/etc/mysql-backup-post" #===================================================================== # Options documantation #===================================================================== # Set USERNAME and PASSWORD of a user that has at least SELECT permission # to ALL databases. # # Set the DBHOST option to the server you wish to backup, leave the # default to backup "this server".(to backup multiple servers make # copies of this file and set the options for that server) # # Put in the list of DBNAMES(Databases)to be backed up. If you would like # to backup ALL DBs on the server set DBNAMES="all".(if set to "all" then # any new DBs will automatically be backed up without needing to modify # this backup script when a new DB is created). # # If the DB you want to backup has a space in the name replace the space # with a % e.g. "data base" will become "data%base" # NOTE: Spaces in DB names may not work correctly when SEPDIR=no. # # You can change the backup storage location from /backups to anything # you like by using the BACKUPDIR setting.. # # The MAILCONTENT and MAILADDR options and pretty self explanitory, use # these to have the backup log mailed to you at any email address or multiple # email addresses in a space seperated list. # (If you set mail content to "log" you will require access to the "mail" program # on your server. If you set this to "files" you will have to have mutt installed # on your server. If you set it to "stdout" it will log to the screen if run from # the console or to the cron job owner if run through cron. If you set it to "quiet" # logs will only be mailed if there are errors reported. ) # # MAXATTSIZE sets the largest allowed email attachments total (all backup files) you # want the script to send. This is the size before it is encoded to be sent as an email # so if your mail server will allow a maximum mail size of 5MB I would suggest setting # MAXATTSIZE to be 25% smaller than that so a setting of 4000 would probably be fine. # # Finally copy automysqlbackup.sh to anywhere on your server and make sure # to set executable permission. You can also copy the script to # /etc/cron.daily to have it execute automatically every night or simply # place a symlink in /etc/cron.daily to the file if you wish to keep it # somwhere else. # NOTE:On Debian copy the file with no extention for it to be run # by cron e.g just name the file "automysqlbackup" # # Thats it.. # # # === Advanced options doc's === # # The list of MDBNAMES is the DB's to be backed up only monthly. You should # always include "mysql" in this list to backup your user/password # information along with any other DBs that you only feel need to # be backed up monthly. (if using a hosted server then you should # probably remove "mysql" as your provider will be backing this up) # NOTE: If DBNAMES="all" then MDBNAMES has no effect as all DBs will be backed # up anyway. # # If you set DBNAMES="all" you can configure the option DBEXCLUDE. Other # wise this option will not be used. # This option can be used if you want to backup all dbs, but you want # exclude some of them. (eg. a db is to big). # # Set CREATE_DATABASE to "yes" (the default) if you want your SQL-Dump to create # a database with the same name as the original database when restoring. # Saying "no" here will allow your to specify the database name you want to # restore your dump into, making a copy of the database by using the dump # created with automysqlbackup. # NOTE: Not used if SEPDIR=no # # The SEPDIR option allows you to choose to have all DBs backed up to # a single file (fast restore of entire server in case of crash) or to # seperate directories for each DB (each DB can be restored seperately # in case of single DB corruption or loss). # # To set the day of the week that you would like the weekly backup to happen # set the DOWEEKLY setting, this can be a value from 1 to 7 where 1 is Monday, # The default is 6 which means that weekly backups are done on a Saturday. # # COMP is used to choose the copmression used, options are gzip or bzip2. # bzip2 will produce slightly smaller files but is more processor intensive so # may take longer to complete. # # COMMCOMP is used to enable or diable mysql client to server compression, so # it is useful to save bandwidth when backing up a remote MySQL server over # the network. # # LATEST is to store an additional copy of the latest backup to a standard # location so it can be downloaded bt thrid party scripts. # # If the DB's being backed up make use of large BLOB fields then you may need # to increase the MAX_ALLOWED_PACKET setting, for example 16MB.. # # When connecting to localhost as the DB server (DBHOST=localhost) sometimes # the system can have issues locating the socket file.. This can now be set # using the SOCKET parameter.. An example may be SOCKET=/private/tmp/mysql.sock # # Use PREBACKUP and POSTBACKUP to specify Per and Post backup commands # or scripts to perform tasks either before or after the backup process. # # #===================================================================== # Backup Rotation.. #===================================================================== # # Daily Backups are rotated weekly.. # Weekly Backups are run by default on Saturday Morning when # cron.daily scripts are run...Can be changed with DOWEEKLY setting.. # Weekly Backups are rotated on a 5 week cycle.. # Monthly Backups are run on the 1st of the month.. # Monthly Backups are NOT rotated automatically... # It may be a good idea to copy Monthly backups offline or to another # server.. # #===================================================================== # Please Note!! #===================================================================== # # I take no resposibility for any data loss or corruption when using # this script.. # This script will not help in the event of a hard drive crash. If a # copy of the backup has not be stored offline or on another PC.. # You should copy your backups offline regularly for best protection. # # Happy backing up... # #===================================================================== # Restoring #===================================================================== # Firstly you will need to uncompress the backup file. # eg. # gunzip file.gz (or bunzip2 file.bz2) # # Next you will need to use the mysql client to restore the DB from the # sql file. # eg. # mysql --user=username --pass=password --host=dbserver database < /path/file.sql # or # mysql --user=username --pass=password --host=dbserver -e "source /path/file.sql" database # # 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. # # Lets hope you never have to use this.. :) # #===================================================================== # Change Log #===================================================================== # # VER 2.5 - (2006-01-15) # Added support for setting MAXIMUM_PACKET_SIZE and SOCKET parameters (suggested by Yvo van Doorn) # VER 2.4 - (2006-01-23) # Fixed bug where weekly backups were not being rotated. (Fix by wolf02) # Added hour an min to backup filename for the case where backups are taken multiple # times in a day. NOTE This is not complete support for mutiple executions of the script # in a single day. # Added MAILCONTENT="quiet" option, see docs for details. (requested by snowsam) # Updated path statment for compatibility with OSX. # Added "LATEST" to additionally store the last backup to a standard location. (request by Grant29) # VER 2.3 - (2005-11-07) # Better error handling and notification of errors (a long time coming) # Compression on Backup server to MySQL server communications. # VER 2.2 - (2004-12-05) # Changed from using depricated "-N" to "--skip-column-names". # Added ability to have compressed backup's emailed out. (code from Thomas Heiserowski) # Added maximum attachment size setting. # VER 2.1 - (2004-11-04) # Fixed a bug in daily rotation when not using gzip compression. (Fix by Rob Rosenfeld) # VER 2.0 - (2004-07-28) # Switched to using IO redirection instead of pipeing the output to the logfile. # Added choice of compression of backups being gzip of bzip2. # Switched to using functions to facilitate more functionality. # Added option of either gzip or bzip2 compression. # VER 1.10 - (2004-07-17) # Another fix for spaces in the paths (fix by Thomas von Eyben) # Fixed bug when using PREBACKUP and POSTBACKUP commands containing many arguments. # VER 1.9 - (2004-05-25) # Small bug fix to handle spaces in LOGFILE path which contains spaces (reported by Thomas von Eyben) # Updated docs to mention that Log email can be sent to multiple email addresses. # VER 1.8 - (2004-05-01) # Added option to make backups restorable to alternate database names # meaning that a copy of the database can be created (Based on patch by Rene Hoffmann) # Seperated options into standard and advanced. # Removed " from single file dump DBMANES because it caused an error but # this means that if DB's have spaces in the name they will not dump when SEPDIR=no. # Added -p option to mkdir commands to create multiple subdirs without error. # Added disk usage and location to the bottom of the backup report. # VER 1.7 - (2004-04-22) # Fixed an issue where weelky backups would only work correctly if server # locale was set to English (issue reported by Tom Ingberg) # used "eval" for "rm" commands to try and resolve rotation issues. # Changed name of status log so multiple scripts can be run at the same time. # VER 1.6 - (2004-03-14) # Added PREBACKUP and POSTBACKUP command functions. (patch by markpustjens) # Added support for backing up DB's with Spaces in the name. # (patch by markpustjens) # VER 1.5 - (2004-02-24) # Added the ability to exclude DB's when the "all" option is used. # (Patch by kampftitan) # VER 1.4 - (2004-02-02) # Project moved to Sourceforge.net # VER 1.3 - (2003-09-25) # Added support for backing up "all" databases on the server without # having to list each one seperately in the configuration. # Added DB restore instructions. # VER 1.2 - (2003-03-16) # Added server name to the backup log so logs from multiple servers # can be easily identified. # VER 1.1 - (2003-03-13) # Small Bug fix in monthly report. (Thanks Stoyanski) # Added option to email log to any email address. (Inspired by Stoyanski) # Changed Standard file name to .sh extention. # Option are set using yes and no rather than 1 or 0. # VER 1.0 - (2003-01-30) # Added the ability to have all databases backup to a single dump # file or seperate directory and file for each database. # Output is better for log keeping. # VER 0.6 - (2003-01-22) # Bug fix for daily directory (Added in VER 0.5) rotation. # VER 0.5 - (2003-01-20) # Added "daily" directory for daily backups for neatness (suggestion by Jason) # Added DBHOST option to allow backing up a remote server (Suggestion by Jason) # Added "--quote-names" option to mysqldump command. # Bug fix for handling the last and first of the year week rotation. # VER 0.4 - (2002-11-06) # Added the abaility for the script to create its own directory structure. # VER 0.3 - (2002-10-01) # Changed Naming of Weekly backups so they will show in order. # VER 0.2 - (2002-09-27) # Corrected weekly rotation logic to handle weeks 0 - 10 # VER 0.1 - (2002-09-21) # Initial Release # #===================================================================== #===================================================================== #===================================================================== # # Should not need to be modified from here down!!
