I want to backup files from a continuously measuring instrument (location in time zone utc+8) to a ftp server (location in time zone utc+1 .. so... far away). The instrument produces approximately 100 MB/day. A new file at least every 24 hours.
2 problems came up so that I think I cannot simply use the synchronize command:
(1) The maximum available disk space available on the ftp server is 2 GB and I am not the only one using this disc space
(2) With regard to (1) the data will be moved to an other server. So the synchronize command will "see" that there are no identical files on the remote system and will copy all files, which will soon be too much ...
Don't ask me why the available space on the ftp server cannot be increased... I simply have to deal with it.
I cannot write to the other server directly, as this needs a vpn connection which is not possible for the instrument (in fact it causes trouble if the same vpn login is used twice and I need it by myself).
Does anyone have an idea how I can backup my measured data?
P.S.: It will take several hours until I can answer here again, as I am actually in time zone UTC+8 and will go to sleep now ;) ..but I am looking forward to see a lot of great ideas to solve my problem after breackfast tomorrow morning :D
