backup, tar and upload ftp
I tried to backup my account using tar and upload it through ftp using a pipe, as I do not have enough space to make the tar.gz first. I need to upload it "real time"... so I used this command
I log to my ftp server, using simple "ftp" linux command and then
put |"tar cvzf - ./" backup.tar.gz
this should work correctly, but I have a problem... the data I have to transfer is over 1 GB and this "put" command takes a lot of time (client and server are not on the same LAN, I use internet to transfer data) and so, for some reason, the connection drops.
Anyone knows a way to split a tar in multiple pieces and submit them via ftp? I know that tar permits to create multiple archives, but I would have to keep them locally (and I don't have enough space...), so this solution is wrong.
I thought of creating a script that:
- create a piece of tar locally (let's say 100MB)
- send it through ftp (maybe using lftp that allows batch process)
- once send is successful, deletes the "temporary" tar-piece created
- creates another 100MB tar skipping what has already been submitted and the process start again from beginning till end of tars
but...I don't know if there's a way to create a tar-piece "skipping" a number of bytes (at least I don't know that way and I found no info about it...)...
anyone knows how to accomplish that?
Or maybe a better solution...
