rocknroll - Rsync fOr baCKup and Roll
Incremental backup maker based on rsync.
rocknroll --init n tag dstdir
rocknroll [options] tag srcdir dstdir
rocknroll backups a remote directories tree srcdir in dstdir onto the local host. For this backup, it manages a set of archives, named tag.1, tag.2, etc. Using the famous 'link-dest' option of rsync, it keeps only the difference between the different archives.
A dstdir can contain several tagged sequences of archive. For example, a dstdir can contain 2 archive sets named daily.1 daily.2 daily.3 daily.4 daily.5 daily.6 daily.7 and week.1 week.2 week.3 week.4.
Before a dstdir can be able to store an archive sequence, it must be formatted with the --init option.
- --init n
format a backup directory to receive n archives. Needed before a dstdir can be used.
- -c config_file
use an alternate config file. By default, rocknroll.conf is searched in @, @/../etc, /etc, where @ is the directory contained the rocknroll binary.
start again with an existing .tag.running archive (useful after an abort)
don't perfom any action, just say what it could be done
- --link-dest dir
by default the link-dest option is set to the tag.1 directory name. This option is to bypass this default.
- --mail_from email
set the email address of the sender for the mail alerts
- --mail_to email
set the email address of the recipient for the mail alerts
- --max_runtime time_in_second
set the max among of time that a backup can take. Older than this value, a .tag.running temporary directory will be deleted.
don't specify a --link-dest tag.1 option to rsync
don't roll up the archives set
only update the archive tag.1 (without deletion of any files on it). Don't roll up the archives set.
- --rsync_retcode_ok n,n,n,n
specify a list of return codes of rsync considered as OK codes. Each code not specified with --rsync_retcode_ok or --rsync_retcode_warn is considered as an error return code.
- --rsync_retcode_warn n,n,n
specify a list of return codes of rsync considered as warning codes. Each code not specified with --rsync_retcode_ok or --rsync_retcode_warn is considered as an error return code.
- --ro "--opt1 --opt2 --opt3"
pass some options to rsync (useful only in argument of command line)
- --ro_default "--opt1 --opt2"
pass some options to rsync (useful only in config file)
- --send_warn 0/1
send alert on warning (default is send alert only on error)
- --smtp_server smtp_server
set the SMTP server
update archive tag.1 (with deletion of obsolete files). Don't roll up archives set.
enable talk to syslog
A configuration file rocknroll.conf, located in @, @/../etc, /etc, where @ is the directory contained the rocknroll binary, can contain any of the preceeding options. The format of a line is : option=value. A # starts a comment.
a control file located in the backup directory, related to the tag archive set.
the temporary directory (located in the archive directory) for the running rsync.
rsnapshot, http://rsnapshot.org. rsnapshot and rocknroll have similar functionalities, and rsnapshot has been the first on the place. But when I began to think about rocknroll, I've never heard of rnspashot.
