    Hello,

    i want to ask if its doable to make backup of local files (tar.gz) without writing these backup files to local disk, but creating these archives right on remote backup server, i want to use tar, not rsync or similar.

    What i found is sshfs which can mount remote folder as local folder, but the quesiton is if that tarring is done without writting on local disk if i set destination fodler that one i mounted by sshfs? or any other way to not write to local disk? thx

    Why not just pull data from the backup server?

    Well I don't think it would be possible as while you are archiving files atleast tmp files would be created and that would be definitely on local system. So what you want is not doable.

    what about adding pipe and ssh after tar command like:
    or:
    tar still does need to write to local disk during its operation? is tar actually writing on source HDD if i select other HDD as a destination in tar command?

    well even if you give final path as on remote disk till its overwritten there, it would create a temp file until complete operation. So if you are not concerned about that temp file then its ok, but that temp file would also take some space and I think you are concerned about it.

    Why not use R1Soft Backups, they're very efficient and they don't write anything on the disk when they run.
    Basically after the first initial backup, every other backup ran after that compares the changes made on your disk (blocks) and saves only those to a remote server automatically... which means way less stress on your server every time the backups are ran cos it doesn't compile them all from scratch and it won't write anything on your SSD.

    There are services out there that offer R1Soft License along with about 200GB backup space on their servers for just $8/month.
