fsbackup - file system backup and synchronization utility.


SYNOPSIS [options] <configuration file>

DESCRIPTION is a incremental backup creation utility. support backup compression and encryption. Backup can be stored on local file system and on remote host stored over SSH or FTP. Some addition scripts allow backups SQL tables from PostgreSQL and MySQL ( and, save system configuration files and list of installed packages ( Backuped with files can be recovered by script, backuped with system packeges can be reinstalled by


The following command-line options can be used with
-n Create new backup without checking files in previously stored hash.
-f Create full backup, like as -n option.
-h Only rebuild hash, no storing files in backup archive.
-c Clean incremental backup storage and create new full backup without checking $cfg_increment_level config parameter.

ADDITION SCRIPTS Backup planner running from crontab. For example:

18 4 * * * /usr/local/fsbackup/ Script to install fsbackup package and some required perl modules. File system backup utility.
cfg_example Example of configuration file.
scripts/ Script for backup SQL tables from PostreSQL and MySQL.
scripts/ Script for store system configuration files and information about installed packages.
scripts/ Script for restore files backuped by
scripts/ Script for reinstall packages stored by


$cfg_backup_name = ’test_host’ Name of backup, single word.
$cfg_cache_dir = ’/usr/local/fsbackup/cache’ Path of internal cache directory for local backup method.
$prog_md5sum = ’md5sum -b’
$prog_tar = ’tar’
$prog_ssh = ’ssh’
$prog_rm = ’rm’
$prog_gzip = ’gzip’
$prog_pgp = ’gpg’ Full path of some external program running from $prog_gzip = ’’ - not use compression, $prog_pgp = ’’ - not use encryption.
$cfg_checksum = ’timesize’ File checksum method:

timesize - checksum of file attributes (default, best speed)

md5 - checksum of file attributes + MD5 checksum of file content.

$cfg_backup_style = ’backup’ Backup style:

backup - incremental backup (copy only new and changed files).

full_backup - full backup (copy all files).

sync - file tree synchronization.

hash - hash creation without storing archive (spying for new or changed files).

$cfg_increment_level = 7 Incremental level (after how many incremental copy make full refresh of backup)
$cfg_type = ’remote_ssh’ Type of backup storage:

    local  - store backup on local file system.
    remote_ssh - store backup on remote host over SSH connection.
    remote_ftp - store backup on remote FTP server.

$cfg_remote_host = ’’
$cfg_remote_login = ’backup_login’
$cfg_remote_path = ’/home/backup_login/backup’ Connection parameters for remote_ssh storage type.
$cfg_remote_password = ’Test1234’ Password of remote login for remote_ftp storage type.
$cfg_remote_ftp_mode = 0 FTP transfer mode. 0 - Active mode, 1 - Passive mode.
$cfg_local_path = ’/var/backup/’ Path of directory to store backup on local file system for local storage type.
$cfg_time_limit = 0 Limit of file creation time in days. If not 0, don’t backup files created or modified later then $cfg_time_limit (days).
$cfg_size_limit = 0 Limit of maximum file size. If not 0, don’t backup files witch size more then $cfg_time_limit kilobytes.
$cfg_root_path = ’/’ Root path for initial chdir.
$cfg_pgp_userid = ’’ Name of user in public key ring with public key will be used for PGP encryption. Not use encryption if not set.
$cfg_verbose = 3 Verbose level.

    0   - Silent mode, suspend all output, except fatal configuration errors.
    1   - Output errors and warnings.
    2   - Output all the  available  data.

$cfg_save_old_backup = 1 Save previous backup to OLD directory before rotation or before storing full backup.

    0 - dont save old backup
    1 - save old backup.

$cfg_maximum_archive_size = 0 Size of maximum size (in KiloBytes) of single unpacked archive file (0 - unlimited file size).
$cfg_stopdir_prune = 0 Recursive review of the prohibited directories.
0 - Recursively to view all contents of directories marked for backup, including contents of directories prohibited by ’!’, ’!d’ and ’=! rules.
1 - not use a recursive entrance to directory prohibited for backup (speed is increased, reduces flexibility of customization).
__DATA__ - list of backuped path and regexp mask.

    /dir[/file] - backup file or directory.
    !/dir[/file] - NOT include this file or directory to backup.
    # - ignore this line.


    =~ - regexp mask for include file or directory to backup.
    f~ - regexp file mask for include file to backup.
    d~ - regexp directory mask for include directory to backup.
    =! - regexp mask for NOT include file or directory to backup.
    f! - regexp file mask for NOT include file to backup.
    d! - regexp directory mask for NOT include directory to backup.

Operation priority:

    1. =!
    2. f!
    3. f~
    4. d!
    5. =~
    6. d~
