To copy the file file. In all cases with standard configuration, you will be prompted to enter your passphrase of the remote user. This command will copy file. Copying a directory remotely is similar to copying a directory locally. Assuming you have write permissions on the host Rsync can run as a daemon rsyncd listening on default port for incoming connections. The following description explains how to create an Rsync server on jupiter with a backup target.
This target can be used to store your backups. To create an Rsync server, do the following:. On jupiter, create a directory to store all your backup files. Specify ownership. In this case, the directory is owned by user tux in group users :. This makes it easier to add additional targets later. These files should not contain any references to global values. The backup target. You can use any name you like. Specifies the user name or group name that is used when the file transfer takes place.
Defines the path to store your backups from Step 1. Specifies a comma-separated list of allowed users. In its simplest form, it contains the user names that are allowed to connect to this module.

Where is it? And another question is it better to have for backup another machine or it's the same to have it on the same machine. What are advantages and disadvantages of first option and what are for second option. Find More Posts by klemen. For the backup question, A true backup in my opinion is a datas duplication from one drive to another drive with the exact same specs and which will be located in another place. You will see that it does not install rsyncd.
The default is true. This option was added to accommodate rsync running on the Windows operating system. The "hosts allow" option allows you to specify a list of patterns that are matched against a connecting clients hostname and IP address. If none of the patterns match then the connection is rejected.
In this case the incoming machines IP address must match exactly. All IP addresses which match the masked IP address will be allowed in. The hostname as determined by a reverse lookup will be matched case insensitive against the pattern. Only an exact match is allowed in. These are matched using the same rules as normal unix filename matching.
If the pattern matches then the client is allowed in. You can also combine "hosts allow" with a separate "hosts deny" option. If both options are specified then the "hosts allow" option s checked first and a match results in the client being able to connect. The "hosts deny" option is then checked and a match means that the host is rejected.
If the host does not match either the "hosts allow" or the "hosts deny" patterns then it is allowed to connect. The default is no "hosts allow" option, which means all hosts can connect. The "hosts deny" option allows you to specify a list of patterns that are matched against a connecting clients hostname and IP address. If the pattern matches then the connection is rejected.
See the "hosts allow" option for more information. The default is no "hosts deny" option, which means all hosts can connect. The "ignore errors" option tells rsyncd to ignore IO errors on the server when deciding whether to run the delete phase of the transfer.
Normally rsync skips the --delete step if any IO errors have occurred in order to prevent disasterous deletion due to a temporary resource shortage or other IO error. In some cases this test is counter productive so you can use this option to turn off this behaviour. This tells the rsync server to completely ignore files that are not readable by the user. This is useful for public archives that may have some non-readable files among the directories, and the sysadmin doesnt want those files to be seen at all.
The "transfer logging" option enables per-file logging of downloads and uploads in a format somewhat similar to that used by ftp daemons. If you want to customize the log formats look at the log format option.
The "log format" option allows you to specify the format used for logging file transfers when transfer logging is enabled. A perl script called rsyncstats to summarize this format is included in the rsync source code distribution. The "timeout" option allows you to override the clients choice for IO timeout for this module. Using this option you can ensure that rsync wont wait on a dead client forever. The timeout is specified in seconds. A value of zero means no timeout and is the default.
A good choice for anonymous rsync servers may be giving a 10 minute timeout. The "refuse options" option allows you to specify a space separated list of rsync command line options that will be refused by your rsync server. The full names of the options must be used i.
When an option is refused, the server prints an error message and exits. The "dont compress" option allows you to select filenames based on wildcard patterns that should not be compressed during transfer. Compression is expensive in terms of CPU usage so it is usually good to not try to compress files that wont compress well, such as already compressed files.
The "dont compress" option takes a space separated list of case-insensitive wildcard patterns. Any source filename matching one of the patterns will not be compressed during transfer. The authentication protocol used in rsync is a bit MD4 based challenge response system. Although I believe that no one has ever demonstrated a brute-force break of this sort of system you should realize that this is not a "military strength" authentication system.
It should be good enough for most purposes but if you want really top quality security then I recommend that you run rsync over ssh. Also note that the rsync server protocol does not currently provide any encryption of the data that is transferred over the link.
Only authentication is provided. Use ssh as the transport if you want encryption. Future versions of rsync may support SSL for better authentication and encryption, but that is still being investigated. A simple rsyncd.
