Hi ALL,

We have 2 Linux boxes that are remote to each other. We need to achieve folder synchronization like whatever we keep in a folder (specific) on Server-A which needs to be replicated to Server-B’s respective folder. The requirements are below
- Secure transfer (encrypted)
- File Compression during transfer
- Resume broken transfer (in case there is connectivity failure or any other break after transferring 50% (500MB – e.g.) of a 1GB size (e.g.). Next time when it is run, it should resume the file and download remaining 500MB part only.
- Authentication
- Detailed Logs containing transferred files (or failed also with reason), time stamp and source/destination folders, server names.

Though there’re few commercial software on Windows (or may be even on Linux), we have to implement by ourselves using shell scripting on Linux only. Though RSYNC is the best option but it fails to provide “resume broken transfers”.

Could anyone please suggest any way/tools/packages/technique to achieve this?

Thanks in Advance

overall, rsync seems to suit best your needs, the only secure application that I can think of, for "Resume broken transfer" is sftp transfer.

Thanks sysgate.

But how could i use SFTP to resume broken transfer? I simulated this and got the entire file re-transferred.

My bad, I've always thought that resuming is supported, because I'm using some in-house modified tools, etc. Sorry for the confusion. Here's an article related to this matter, HTH.
