# ============================================================================ | |
# === SCHEDULING AND RETENTION OPTIONS ( Read the doc's below for details )=== | |
#============================================================================= | |
# Do you want to do hourly backups? How long do you want to keep them? | |
DOHOURLY="no" | |
HOURLYRETENTION=24 | |
# Do you want to do daily backups? How long do you want to keep them? | |
DODAILY="yes" | |
DAILYRETENTION=0 | |
# Which day do you want weekly backups? (1 to 7 where 1 is Monday) | |
DOWEEKLY="yes" | |
WEEKLYDAY=6 | |
WEEKLYRETENTION=4 | |
# Do you want monthly backups? How long do you want to keep them? | |
DOMONTHLY="yes" | |
MONTHLYRETENTION=4 | |
# ============================================================ | |
# === ADVANCED OPTIONS ( Read the doc's below for details )=== | |
#============================================================= | |
# Choose Compression type. (gzip or bzip2) | |
COMP="gzip" | |
# Choose if the uncompressed folder should be deleted after compression has completed | |
CLEANUP="yes" | |
# Additionally keep a copy of the most recent backup in a seperate directory. | |
LATEST="yes" | |
# Make Hardlink not a copy | |
LATESTLINK="yes" | |
# Use oplog for point-in-time snapshotting. | |
OPLOG="yes" | |
# Choose other Server if is Replica-Set Master | |
REPLICAONSLAVE="yes" | |
# Allow DBUSERNAME without DBAUTHDB | |
REQUIREDBAUTHDB="yes" | |
# Maximum files of a single backup used by split - leave empty if no split required | |
# MAXFILESIZE="" | |
# Command to run before backups (uncomment to use) | |
# PREBACKUP="" | |
# Command run after backups (uncomment to use) | |
# POSTBACKUP="" | |
#===================================================================== | |
# Options documentation | |
#===================================================================== | |
# Set DBUSERNAME and DBPASSWORD 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) | |
# | |
# 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 explanatory, 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. ) | |
# | |
# | |
# Finally copy automongobackup.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 "automongobackup" | |
# | |
# Thats it.. | |
# | |
# | |
# === Advanced options === | |
# | |
# To set the day of the week that you would like the weekly backup to happen | |
# set the WEEKLYDAY 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. | |
# | |
# Use PREBACKUP and POSTBACKUP to specify Pre and Post backup commands | |
# or scripts to perform tasks either before or after the backup process. | |
# | |
# | |
#===================================================================== | |
# Backup Rotation.. | |
#===================================================================== | |
# | |
# Hourly backups are executed if DOHOURLY is set to "yes". | |
# The number of hours backup copies to keep for each day (i.e. 'Monday', 'Tuesday', etc.) is set with DHOURLYRETENTION. | |
# DHOURLYRETENTION=0 rotates hourly backups every day (i.e. only the most recent hourly copy is kept). -1 disables rotation. | |
# | |
# Daily backups are executed if DODAILY is set to "yes". | |
# The number of daily backup copies to keep for each day (i.e. 'Monday', 'Tuesday', etc.) is set with DAILYRETENTION. | |
# DAILYRETENTION=0 rotates daily backups every week (i.e. only the most recent daily copy is kept). -1 disables rotation. | |
# | |
# Weekly backups are executed if DOWEEKLY is set to "yes". | |
# WEEKLYDAY [1-7] sets which day a weekly backup occurs when cron.daily scripts are run. | |
# Rotate weekly copies after the number of weeks set by WEEKLYRETENTION. | |
# WEEKLYRETENTION=0 rotates weekly backups every week. -1 disables rotation. | |
# | |
# Monthly backups are executed if DOMONTHLY is set to "yes". | |
# Monthy backups occur on the first day of each month when cron.daily scripts are run. | |
# Rotate monthly backups after the number of months set by MONTHLYRETENTION. | |
# MONTHLYRETENTION=0 rotates monthly backups upon each execution. -1 disables rotation. | |
# | |
#===================================================================== | |
# 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. You | |
# should copy your backups offline or to another PC for best protection. | |
