  111. #=====================================================================
  112. # Options documentation
  113. #=====================================================================
  114. # Set USERNAME and PASSWORD of a user that has at least SELECT permission
  115. # to ALL databases.
  116. #
  117. # Set the DBHOST option to the server you wish to backup, leave the
  118. # default to backup "this server".(to backup multiple servers make
  119. # copies of this file and set the options for that server)
  120. #
  121. # Put in the list of DBNAMES(Databases)to be backed up. If you would like
  122. # to backup ALL DBs on the server set DBNAMES="all".(if set to "all" then
  123. # any new DBs will automatically be backed up without needing to modify
  124. # this backup script when a new DB is created).
  125. #
  126. # If the DB you want to backup has a space in the name replace the space
  127. # with a % e.g. "data base" will become "data%base"
  128. # NOTE: Spaces in DB names may not work correctly when SEPDIR=no.
  129. #
  130. # You can change the backup storage location from /backups to anything
  131. # you like by using the BACKUPDIR setting..
  132. #
  133. # The MAILCONTENT and MAILADDR options and pretty self explanitory, use
  134. # these to have the backup log mailed to you at any email address or multiple
  135. # email addresses in a space seperated list.
  136. # (If you set mail content to "log" you will require access to the "mail" program
  137. # on your server. If you set this to "files" you will have to have mutt installed
  138. # on your server. If you set it to "stdout" it will log to the screen if run from
  139. # the console or to the cron job owner if run through cron. If you set it to "quiet"
  140. # logs will only be mailed if there are errors reported. )
  141. #
  142. # MAXATTSIZE sets the largest allowed email attachments total (all backup files) you
  143. # want the script to send. This is the size before it is encoded to be sent as an email
  144. # so if your mail server will allow a maximum mail size of 5MB I would suggest setting
  145. # MAXATTSIZE to be 25% smaller than that so a setting of 4000 would probably be fine.
  146. #
  147. # Finally copy autopostgresqlbackup.sh to anywhere on your server and make sure
  148. # to set executable permission. You can also copy the script to
  149. # /etc/cron.daily to have it execute automatically every night or simply
  150. # place a symlink in /etc/cron.daily to the file if you wish to keep it
  151. # somwhere else.
  152. # NOTE:On Debian copy the file with no extention for it to be run
  153. # by cron e.g just name the file "autopostgresqlbackup"
  154. #
  155. # Thats it..
  156. #
  157. #
  158. # === Advanced options doc's ===
  159. #
  160. # The list of MDBNAMES is the DB's to be backed up only monthly. You should
  161. # always include "template1" in this list to backup the default database
  162. # template used to create new databases.
  163. # NOTE: If DBNAMES="all" then MDBNAMES has no effect as all DBs will be backed
  164. # up anyway.
  165. #
  166. # If you set DBNAMES="all" you can configure the option DBEXCLUDE. Other
  167. # wise this option will not be used.
  168. # This option can be used if you want to backup all dbs, but you want
  169. # exclude some of them. (eg. a db is to big).
  170. #
  171. # Set CREATE_DATABASE to "yes" (the default) if you want your SQL-Dump to create
  172. # a database with the same name as the original database when restoring.
  173. # Saying "no" here will allow your to specify the database name you want to
  174. # restore your dump into, making a copy of the database by using the dump
  175. # created with autopostgresqlbackup.
  176. # NOTE: Not used if SEPDIR=no
  177. #
  178. # The SEPDIR option allows you to choose to have all DBs backed up to
  179. # a single file (fast restore of entire server in case of crash) or to
  180. # seperate directories for each DB (each DB can be restored seperately
  181. # in case of single DB corruption or loss).
  182. #
  183. # To set the day of the week that you would like the weekly backup to happen
  184. # set the DOWEEKLY setting, this can be a value from 1 to 7 where 1 is Monday,
  185. # The default is 6 which means that weekly backups are done on a Saturday.
  186. #
  187. # COMP is used to choose the copmression used, options are gzip or bzip2.
  188. # bzip2 will produce slightly smaller files but is more processor intensive so
  189. # may take longer to complete.
  190. #
  191. # COMMCOMP is used to set the compression level (from 0 to 9, 0 means no compression)
  192. # between the client and the server, so it is useful to save bandwidth when backing up
  193. # a remote PostgresSQL server over the network.
  194. #
  195. # LATEST is to store an additional copy of the latest backup to a standard
  196. # location so it can be downloaded bt thrid party scripts.
  197. #
  198. # Use PREBACKUP and POSTBACKUP to specify Per and Post backup commands
  199. # or scripts to perform tasks either before or after the backup process.
  200. #
  201. #
  202. #=====================================================================
  203. # Backup Rotation..
  204. #=====================================================================
  205. #
  206. # Daily Backups are rotated weekly..
  207. # Weekly Backups are run by default on Saturday Morning when
  208. # cron.daily scripts are run...Can be changed with DOWEEKLY setting..
  209. # Weekly Backups are rotated on a 5 week cycle..
  210. # Monthly Backups are run on the 1st of the month..
  211. # Monthly Backups are NOT rotated automatically...
  212. # It may be a good idea to copy Monthly backups offline or to another
  213. # server..
  214. #
  215. #=====================================================================
  216. # Please Note!!
  217. #=====================================================================
  218. #
  219. # I take no resposibility for any data loss or corruption when using
  220. # this script..
  221. # This script will not help in the event of a hard drive crash. If a
  222. # copy of the backup has not be stored offline or on another PC..
  223. # You should copy your backups offline regularly for best protection.
  224. #
  225. # Happy backing up...
  226. #
  227. #=====================================================================
  228. # Restoring
  229. #=====================================================================
  230. # Firstly you will need to uncompress the backup file.
  231. # eg.
  232. # gunzip file.gz (or bunzip2 file.bz2)
  233. #
  234. # Next you will need to use the postgresql client to restore the DB from the
  235. # sql file.
  236. # eg.
  237. # psql --host dbserver --dbname database < /path/file.sql
  238. #
  239. # NOTE: Make sure you use "<" and not ">" in the above command because
  240. # you are piping the file.sql to psql and not the other way around.
  241. #
  242. # Lets hope you never have to use this.. :)
