||
694 | |||
695 | fsbackup - file system backup and synchronization utility. |
||
696 | |||
697 | =head1 SYNOPSIS |
||
698 | |||
699 | fsbackup.pl [options] <configuration file> |
||
700 | |||
701 | =head1 DESCRIPTION |
||
702 | |||
703 | C<fsbackup.pl> is a incremental backup creation utility. |
||
704 | C<fsbackup.pl> support backup compression and encryption. Backup can be stored |
||
705 | on local file system and on remote host stored over SSH or FTP. Some addition |
||
706 | scripts allow backups SQL tables from PostgreSQL and MySQL (C<pgsql_backup.sh> |
||
707 | and C<mysql_backup.sh>)), save system configuration files and list of installed |
||
708 | packages (C<sysbackup.sh>). |
||
709 | Backuped with C<fsbackup.pl> files can be recovered by script C<fsrestore.sh>, |
||
710 | backuped with C<sysbackup.sh> system packeges can be reinstalled by C<sysrestore.sh> |
||
711 | |||
712 | =head1 OPTIONS |
||
713 | |||
714 | The following command-line options can be used with C<fsbackup.pl>: |
||
715 | |||
716 | =over |
||
717 | |||
718 | =item C<-n> |
||
719 | |||
720 | Create new backup without checking files in previously stored hash. |
||
721 | |||
722 | =item C<-f> |
||
723 | |||
724 | Create full backup, like as C<-n> option. |
||
725 | |||
726 | =item C<-h> |
||
727 | |||
728 | Only rebuild hash, no storing files in backup archive. |
||
729 | |||
730 | =item C<-c> |
||
731 | |||
732 | Clean incremental backup storage and create new full backup without checking |
