Hi

Can anyone suggest a program that will download files from different hosting sites by ftp and arhivate them locally?

It would be great if it will have per host/per site rules and schedule.
Possibility to configure time period or number of backups to keep per site.
Possibility to make incremental backups.
Possibility to generate some kind of successful /unsuccessful report and to send them to email.
Possibility to download backups simultaneously.

p.s. for now I am using several cron scripts running lftp with mirror command, but may be there is some kind of manager?

Are you saying "ftp" because you are strictly limited to something using that exact protocol, or are you saying "ftp" generically to refer to anything that involves file transfers?

If the latter, I recommend "rsync". It has a couple nice advantages. One is that it avoids repeating a transfer of a file it already has (or if it has parts of a file that was incomplete or has changed, it transfers only what it needs). The other is that it can "backup" what is deleted or replaced to another directory, allowing a "reverse restore" archiving of incrementals (use a dated directory for each day's run and you build a history of daily file versions, and can prune the archive at the oldest point). A third advantage is that is can more gracefully be run through tunneled connections since it does not need to establish a 2nd connection for the data.

yes I'm limited to use ftp
I like rsync but can't use it here
