###### (L) 2013-2014 by Orsiris "Ozy" de Jong (www.netpower.fr)
###### Config file rev 1304201501

## ---------- GENERAL OPTIONS

## Sync job identification
SYNC_ID="sync_test"

## Directories to synchronize. Master must be on the system Osync runs on. Slave can be either a local directory, or a remote one.
MASTER_SYNC_DIR="/home/git/osync/dir1"
SLAVE_SYNC_DIR="/home/git/osync/dir2"
#SLAVE_SYNC_DIR="ssh://backupuser@yourhost.old:22//home/git/osync/dir2"
## If slave replica is a remote directory, you must specify a RSA key (please use full path). Please see documentation for further information.
SSH_RSA_PRIVATE_KEY="/home/backupuser/.ssh/id_rsa"

## Create sync directories if they do not exist
CREATE_DIRS=no

## Log file location. Leaving this empty will create a logfile at /var/log/osync_version_SYNC_ID.log (or current directory if /var/log doesn't exist)
LOGFILE=""


## List of directories to exclude from sync on both sides (rsync patterns, wildcards work).
## Paths are relative to sync dirs. List elements are separated by a semicolon.
RSYNC_EXCLUDE_PATTERN=""
#RSYNC_EXCLUDE_PATTERN="tmp;archives"

## File that contains the list of directories or files to exclude from sync on both sides. Leave this empty if you don't want to use an exclusion file.
## This file has to be in the same directory as the config file
## Paths are relative to sync dirs. One element per line.
RSYNC_EXCLUDE_FROM=""
#RSYNC_EXCLUDE_FROM="exclude.list"

## List elements separator char.  You may set an alternative separator char for your directories lists above.
PATH_SEPARATOR_CHAR=";"

## Generate an alert if master or slave replicas have less free space than given value in KB.
MINIMUM_SPACE=10240

## Bandwidth limit Kbytes / second. Leave 0 to disable limitation
BANDWIDTH=0

## If enabled, synchronization on remote system will be processed as superuser. See documentation for /etc/sudoers file configuration.
SUDO_EXEC=no
## Paranoia option. Don't change this unless you read the documentation.
RSYNC_EXECUTABLE=rsync

## ---------- REMOTE SYNC OPTIONS

## ssh compression should be used unless your remote connection is good enough (LAN)
SSH_COMPRESSION=yes

## Check for connectivity to remote host before launching remote sync task. Be sure the hosts responds to ping. Failing to ping will stop sync.
REMOTE_HOST_PING=no

## Check for internet access by pinging one or more 3rd party hosts before remote sync task. Leave empty if you don't want this check to be be performed. Failing to ping will stop sync.
## If you use this function, you should set more than one 3rd party host, and be sure you can ping them.
## Be aware some DNS like opendns redirect false hostnames. Also, this adds an extra execution time of a bit less than a minute.
REMOTE_3RD_PARTY_HOSTS="www.kernel.org www.google.com"

## Remote rsync executable path. Leave this empty in most cases
RSYNC_REMOTE_PATH=""

## ---------- MISC OPTIONS

## Preserve ACLS. Make sure source and target FS can manage same ACLs or you'll get loads of errors.
PRESERVE_ACL=no
## Preserve Xattr. Make sure source and target FS can manage same Xattrs or you'll get loads of errors.
PRESERVE_XATTR=no
## Transforms symlinks into referent files/dirs
COPY_SYMLINKS=no
## Treat symlinked dirs	as dirs. CAUTION: This also follows symlinks outside of the replica root.
KEEP_DIRLINKS=no
## Preserve hard links. Make sure source and target FS can manage hard links or you will lose them.
PRESERVE_HARDLINKS=no
## Do a full checksum on all files that have identical sizes, they are checksummed to see if they actually are identical. This can take a long time.
CHECKSUM=no

## Let RSYNC compress file transfers. Do not use this if both master and slave replicas are on local system. Also,  do not use this if you already enabled SSH compression.
RSYNC_COMPRESS=yes

## Maximum execution time (in seconds) for sync process. Soft exec time only generates a warning. Hard exec time will generate a warning and stop sync process.
SOFT_MAX_EXEC_TIME=7200
HARD_MAX_EXEC_TIME=10600

## Minimum time (in seconds) in file monitor /daemon mode between modification detection and sync task in order to let copy operations finish.
MIN_WAIT=60

## Maximum time (in seconds) waiting in file monitor / daemon mode. After this time, sync is run.
## Use 0 to wait indefinitely.
MAX_WAIT=300

## ---------- BACKUP AND DELETION OPTIONS

## Enabling this option will keep a backup of a file on the target replica if it gets updated from the source replica. Backups will be made to .osync_workdir/backups
CONFLICT_BACKUP=yes
## Keep multiple backup versions of the same file. Warning, This can be very space consuming.
CONFLICT_BACKUP_MULTIPLE=no
## Osync will clean backup files after a given number of days. Setting this to 0 will disable cleaning and keep backups forever. Warning: This can be very space consuming.
CONFLICT_BACKUP_DAYS=30
## If the same file exists on both replicas, newer version will be synced. However, if both files have the same timestamp but differ, CONFILCT_PREVALANCE sets winner replica.
CONFLICT_PREVALANCE=master

## On deletion propagation to the target replica, a backup of the deleted files can be kept. Deletions will be kept in .osync_workdir/deleted
SOFT_DELETE=yes
## Osync will clean deleted files after a given number of days. Setting this to 0 will disable cleaning and keep deleted files forever. Warning: This can be very space consuming.
SOFT_DELETE_DAYS=30

## ---------- RESUME OPTIONS

## Try to resume an aborted sync task
RESUME_SYNC=yes
## Number maximum resume tries before initiating a fresh sync.
RESUME_TRY=2
## When a pidlock exists on slave replica that does not correspond to master's sync-id, force pidlock removal. Be careful with this option if you have multiple masters.
FORCE_STRANGER_LOCK_RESUME=no

## Keep partial uploads that can be resumed on next run, experimental feature
PARTIAL=no

## ---------- ALERT OPTIONS

## List of alert mails separated by spaces
DESTINATION_MAILS="your@alert.tld"

## Windows (MSYS environment) only mail options (used with sendemail.exe from Brandon Zehm)
SENDER_MAIL="alert@your.system.tld"
SMTP_SERVER=smtp.your.isp.tld
SMTP_USER=
SMTP_PASSWORD=

## ---------- EXECUTION HOOKS

## Commands can will be run before and / or after sync process (remote execution will only happen if REMOTE_SYNC is set).
LOCAL_RUN_BEFORE_CMD=""
LOCAL_RUN_AFTER_CMD=""

REMOTE_RUN_BEFORE_CMD=""
REMOTE_RUN_AFTER_CMD=""

## Max execution time of commands before they get force killed. Leave 0 if you don't wan't this to happen. Time is specified in seconds.
MAX_EXEC_TIME_PER_CMD_BEFORE=0
MAX_EXEC_TIME_PER_CMD_AFTER=0

## Stops Osync execution if one of the above commands fail
STOP_ON_CMD_ERROR=yes
