NAME ftpbackup - backup from an ftp server SYNOPSIS ftpbackup [Options] *URL* DESCRIPTION ftpbackup allows to backup all files from an FTP server locally or even on another ftp server. If no destination is specified, ftpbackup tries to save in the current directory. When storing, ftpbackup stores all downloaded files below YYYYMMDD/servername, so you can create a nice little hierachical storage. For each servername, ftpbackup keeps track of a default of 3 backups, removing old backups if necessary. If you want to keep more than 3 backup-version, look at the --keep option. Additionally ftpbackup can try to hardlink each backup with the previous version similar to how rsync does it (in fact, it uses rsync for hardlinking the data). ftpbackup can also encrypt each downloaded file using "gpg --symmetric". If no username/password is specified, ftpbackup will try to authenticat using anonymous logins (this means username=anonymous, firstname.lastname@example.org). OPTIONS --active Use active connection mode. (Default is passive). --destination=*dir* Store the backups below *dir*. Foreach run ftpbackup will create a directory in the date format 'YYYYMMDD' (as date +'%Y%m%d' would create it) and below that directory a directory of the *server*. (e.g. when running on Apr. 4th, 2008 and backing up kernel.org, ftpbackup would create a directory structure *20080404/kernel.org/*) You can enter a ftp url here as well. In this case, ftpbackup will try to make a direct ftp connection from the source ftp server to the destination ftp server and copies all data to the destination ftp server directly. --debug Turn on Debugging Infos. --encrypt This switch enables symmetric encryption using gpg(1). In order for this to work, gpg(1) needs to be installed and available in your path and the perl module GnuPG needs to be installed. If the option --passfile is not specified, ftpbackup will interactively ask for an encryption password. Note that --encrypt will not work, when transfering the data to another ftp server, since the ftp protocoll does not specify such actions. --exclude=*'pattern'* Specify an exclude pattern. You can use perl regular expressions (see perlre(1) for details). It is possible to specify this option several times and each pattern will be applied to all files and directories on the server, skipping each match. --hardlink When storing the data locally, use rsync(1) to store the data. Basically this will call rsync(1) --archive --hard-links --sparse --link-dest=oldbackup *src/* *dest/* This is handy, when automatically downloading regularly, since that will store each version of a file only once. Note, that hardlinking will not work, when transfering to another ftp-server or when trying to encrypt the files. In these cases ftpbackup will silently ignore this option. -h, --help Displays the help screen. --keep=number Only keep *number* version locally, deleting the oldest version. If not specified, ftpbackup will keep 3 versions. --passfile=*file* When encryption has been specified using --encrypt, you can instruct ftpbackup to read *file* for a password. This file needs only to contain the password. ftpbackup will use the whole input as passphrase. --port Specify the FTP Server Port --permission Try to preserve the permissions, as listed by the FTP dir command. This option will simply try to set the same permissions as on the remote ftp server by parsing the rwxrwxrwx String. --[no]recursion By default, ftpbackup will recursively download all files below the given directory. You can turn off recursive downloading using --norecursion --removesrc Try to remove the directory on the FTP server when finished. This depends on the servers configuration and the permissions you have. This happens at the end, after the transfer is finished, so if this fails, you still have all data downloaded completely. --statistics Print a little statistic when finished. NOTES ftpbackup requires perl(1) of version 5.8 or higher. If you want to make use of hardlinking your downloaded backups, ftpbackup needs rsync(1) available in your path and the perl module File::Rsync. For encrypting the downloaded files you'll need the perl module GnuPG and gpg(1) available in your path. FTP URLs ftpbackup expects FTP URLs using the following syntax: *ftp://username:password@server/directory*. If no password is specified, ftpbackup will try to read the users .netrc. If this file does not exist it will ask interactively for the password. If both username and password are not specified, ftpbackup will use anonymous authentication. You can leave out the directory, in which case ftpbackup will simply try to download from the server's root level. EXAMPLES ftpbackup --statistics ftp://ftp.eu.kernel.org/pub/ Download all data from ftp.eu.kernel.org/pub using anonymous access. When finished print a litte statistic summary. ftpbackup --statistics --exclude='\.iso$' ftp://ftp.eu.kernel.org/pub/ Download all files, except iso images, when finished print a little summary. ftpbackup --statistics --exclude='\.iso$' --encrypt --norecursion ftp://ftp.eu.kernel.org/pub/dist/knoppix Download only files in directory knoppix on the kernel server, excluding iso images and locally encrypting the files. You will be asked for a password when run. ftpbackup --destination=ftp://servername/dir --keep=5 --norecursion ftp://ftp.eu.kernel.org/pub/dist/knoppix Download all files in directory knoppix on the kernel server and transfer them to the ftp server servername. All data will be stored in the directory dir. If more than 4 versions exist, the oldest versions will be deleted. BUGS When run several times a day for the same ftp server, ftpbackup will happily overwrite already existing files. ftpbackup does not yet take care of the permissions on the server. So it will create all files as the current user with the default umask. AUTHOR Copyright 2008 by Christian Brabandt <email@example.com> Licensed under the GNU GPL.
