FTP is probably one of the most important InterNet services to transfer files, but be careful - FTP is not the same as FTP! The bad habit of "transferring files via e-mail does not support professionals' defacto! Professionals or laymen who want to be a little bit better than the rest of the world, so please read on here (lay people who want to stay laymen, are wrong here ..):
The application environment is always assumed to be that an FTP client connects to one (or more) FTP server (s) and that data is then to be transferred. If 2 clients want to transfer FTP to each other, one of the PCs must take over the role of the server, or the 2 clients must use an FTP server with their provider (if he provides it). In this case, only the one client has to upload his files to the FTP server and then make the download after a successful upload to the second PC.
The other differences in the use of the FTP protocol are mainly in the nature of the application, ie "for" what "you need FTP and" what "would you like to achieve should be hired every time you use FTP as a consideration. For various applications we mention here some programs, and what you can do with them:
The Microsoft InterNet Explorer 6 + 7 has built a very useful FTP client, which you simply call by typing an FTP: // address. Disadvantages of the InterNet Explorer are very clear that it does not support "secure FTP protocols - eg S-FTP". In addition, it does not contain a download manager that can attach files in the event of an error. Reasonably usable is the IE FTP client so only if you "very small files" wants to transfer, or if you supplemented him with a download manager. For this we recommend "Free Download Manager", which you can download here:
The Firefox browser from Mozilla already contains a much better FTP client, which already contains a built-in download manager for downloading (transfer from server to client) very large files. This is sufficient in most cases for downloading files. Here you do not need to install anything, but a setting in Firefox you should definitely change - Tools - Settings - General: check: "Ask each time, where a file should be saved".
For many users, it's not enough just to be able to download files - they especially need the upload function. Caution: DSL users can often not quickly "upload" because their connection for technical reasons only ISDN speed from the client to InterNet brings ". Wireless network users or users of symmetrical lines have the advantage of making "Uloads" via FTP even at high speed. For this a good ftp client is to be used, eg "Filezilla".
FTP synchronization essentially handles the functionality of comparing 2 directories with their contents (files and subdirectories) (CRC checksums and timestamps of all objects at the source and the destination) and then only comparing these differences against each other. We talk about "one-way synchronization" (source-to-target alignment) and "bidirectional synchronization" (two-way alignment between source and destination to account for changes on both sides)
There are 2 types of tools here. One is the command line tool "WGET Mentions that as a batch job (program) wonderfully "one-sided syncronization" mastered. For more than 10 years, MARTEC-BBS has been replicating FTP servers among each other or transferring logbooks and virus signatures to globally distributed servers. So the tool is absolutely perfect for professionals!
Further - graphically oriented FTP syncronization programs - are the tools "SyncBack „,
FTP backup (backup):
More and more data centers offer backup storage locations (MARTEC-BBS also), where you can save the most important files externally. The absolute requirement here is that the files transferred externally must be highly encrypted, and that the FTP backup program should also be timed.
Here is the reference to the program "backup Maker ", For files to be backed up to max. 1MByte size is "free" (usually enough for the most common files from Office and pictures, etc.) and all the requirements for a FTP backup in perfection mastered - even encryption. If you want to backup files larger than 1 MByte, you need the Pro-Home-Version for 25 EUR, which is certainly designed for serious applications. The big advantage for laymen is, the program is in German and very easy to use!
Likewise, here is the program "MicroBackup2006 "Mentions that in the free variant FTP backup of all file sizes, but for encrypting then offers a registered Pro variant. The tool works by first archiving everything into a local backup directory (in .ZIP format) and then uploading the result of the backup to a server via FTP.
I am often asked, what costs external data storage, eg with an FTP backup.
First, a few words about the procedure: MARTEC operates servers at 2 locations, which replicate (synchronize or synchronize) backed up data with each other. Nothing is played on Baender, but the state of the plates is on the 2 backup servers simply "doubled" provided "- which is sufficient. In addition, the disks are not simple disks, but storage systems that are "duplicated" (mirrored) at each location. Versioning of stands is possible, but then requires duplicate data storage by the user. As an entry point to the storage, it is possible to join both servers (locations) as both have the same status - cleverly connected to 2 different providers. The process is therefore highly secure.
- On the one hand, it must be taken into account in the calculation that data is transferred and that the data is of course lower during a synchronization than during a complete backup. These costs are called transfer costs "synchronization costs" or "backup transfer". Synchronization costs $ 5 per month per 1 gigabyte of data, regardless of how many backups are made. Backup transfer costs € 15 per month per gigabyte and run.
- On the other hand, the data storage and the disk space or their repeated copy to other data carriers (a second server at a different location) implemented at MARTEC, which again opens up data transfer and costs. The data storage costs an additional 20 € per month and per gigabyte.
Sample calculation: If you want to synchronize 1 GB of data, that costs 5 € + 20 € = 25 € per month.
