MDBNAMES="template1 $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 # Command to run before backups (uncomment to use) #PREBACKUP="/etc/pgsql-backup-pre" # Command run after backups (uncomment to use) POSTBACKUP="bash /home/backups/scripts/ftp_pgsql" #===================================================================== # Options documentation #===================================================================== # 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 sto stdout it will log to the screen if run from # the console or to the cron job owner if run through cron) # # 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. # # 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... # #===================================================================== # Change Log #===================================================================== # # VER 1.0 - (2005-03-25) # Initial Release - based on AutoMySQLBackup 2.2 # #===================================================================== #===================================================================== # # Should not need to be modified from here down!!
