Does anybody know if the stock version of the linkstations ftp engine
(firmware 2.05) support any of the below?
The MDTM command has two functions: to get the last modification date
& time of a file, and to set the last modification date & time of a
file. Most servers support getting the date & time, but some do not
support setting the date & time. In this case SyncBackSE has two
options: to change the local files date & time to match that of the
file on the FTP server (the default), or to record the date & time of
the local file in the Fast Backup results (you must enable Fast
Backup and disable the option "Force the file modification date &
time to be correct" on the Copy/Delete tab).
This command is used to retrieve the details of all files and
directories within a directory on the FTP server. If a server
supports this command then SyncBackSE can scan the server
considerably faster. If the server does not support this command then
SyncBackSE must make two extra calls per file to the server. For
example, if a server supports MLSD then only one call to the server
is required per directory, but if it doesn't support MLSD then there
will be one call to get the list of files and sub-directories,
followed by two calls per file in that directory.
A few servers support MODE Z compression. This allows files to be
sent to and retrieved from the server in compressed format. For high
bandwidth connections it's generally not necessary to use MODE Z
compression. Also note that some servers may support MODE Z
compression but the administrators of that server may have disabled
it (as it uses more CPU time and so could overload the server).
Some servers support SSL/TLS encryption (implicit and/or explicit).
If the server does support it then SyncBackSE can securely send and
receive files to and from the server. Note that encryption does
impact performance and so should only be used if required.
FTP is a text protocol, not binary. Therefore it can have problems
with some filenames, e.g. Chinese. To get around this problem some
FTP servers accept filenames in UTF-8. UTF-8 is an ASCII-preserving
encoding method for Unicode (ISO 10646), the Universal Character Set
(UCS). Please note that even though some FTP servers claim to support
UTF8, their implementation of it is either broken or partially
If the server supports the XCRC extension then SyncBackSE can verify
that files transferred to or from the server have been transmitted
correctly, i.e. the file on the FTP server is the same as the local
file based on its CRC value.
