| 718 | =head1 NAME |
||
| 719 | |||
| 720 | fsbackup - file system backup and synchronization utility. |
||
| 721 | |||
| 722 | =head1 SYNOPSIS |
||
| 723 | |||
| 724 | fsbackup.pl [options] <configuration file> |
||
| 725 | |||
| 726 | =head1 DESCRIPTION |
||
| 727 | |||
| 728 | C<fsbackup.pl> is a incremental backup creation utility. |
||
| 729 | C<fsbackup.pl> support backup compression and encryption. Backup can be stored |
||
| 730 | on local file system and on remote host stored over SSH or FTP. Some addition |
||
| 731 | scripts allow backups SQL tables from PostgreSQL and MySQL (C<pgsql_backup.sh> |
||
| 732 | and C<mysql_backup.sh>)), save system configuration files and list of installed |
||
| 733 | packages (C<sysbackup.sh>). |
||
| 734 | Backuped with C<fsbackup.pl> files can be recovered by script C<fsrestore.sh>, |
||
| 735 | backuped with C<sysbackup.sh> system packeges can be reinstalled by C<sysrestore.sh> |
||
| 736 | |||
| 737 | =head1 OPTIONS |
||
| 738 | |||
| 739 | The following command-line options can be used with C<fsbackup.pl>: |
||
| 740 | |||
| 741 | =over |
||
| 742 | |||
| 743 | =item C<-n> |
||
| 744 | |||
| 745 | Create new backup without checking files in previously stored hash. |
||
| 746 | |||
| 747 | =item C<-f> |
||
| 748 | |||
| 749 | Create full backup, like as C<-n> option. |
||
| 750 | |||
| 751 | =item C<-h> |
||
| 752 | |||
| 753 | Only rebuild hash, no storing files in backup archive. |
||
| 754 | |||
| 755 | =item C<-c> |
||
| 756 | |||
| 757 | Clean incremental backup storage and create new full backup without checking |
||
| 758 | $cfg_increment_level config parameter. |
