724 | =head1 NAME |
||
725 | |||
726 | fsbackup - file system backup and synchronization utility. |
||
727 | |||
728 | =head1 SYNOPSIS |
||
729 | |||
730 | fsbackup.pl [options] <configuration file> |
||
731 | |||
732 | =head1 DESCRIPTION |
||
733 | |||
734 | C<fsbackup.pl> is a incremental backup creation utility. |
||
735 | C<fsbackup.pl> support backup compression and encryption. Backup can be stored |
||
736 | on local file system and on remote host stored over SSH or FTP. Some addition |
||
737 | scripts allow backups SQL tables from PostgreSQL and MySQL (C<pgsql_backup.sh> |
||
738 | and C<mysql_backup.sh>)), save system configuration files and list of installed |
||
739 | packages (C<sysbackup.sh>). |
||
740 | Backuped with C<fsbackup.pl> files can be recovered by script C<fsrestore.sh>, |
||
741 | backuped with C<sysbackup.sh> system packeges can be reinstalled by C<sysrestore.sh> |
||
742 | |||
743 | =head1 OPTIONS |
||
744 | |||
745 | The following command-line options can be used with C<fsbackup.pl>: |
||
746 | |||
747 | =over |
||
748 | |||
749 | =item C<-n> |
||
750 | |||
751 | Create new backup without checking files in previously stored hash. |
||
752 | |||
753 | =item C<-f> |
||
754 | |||
755 | Create full backup, like as C<-n> option. |
||
756 | |||
757 | =item C<-h> |
||
758 | |||
759 | Only rebuild hash, no storing files in backup archive. |
||
760 | |||
761 | =item C<-c> |
||
762 | |||
