Currently can sync DB's using HTTP, SMB, FTP, File based or paste-based, we ignores the SMB option due obviously insecure.
Here due special requeriments of sybase replication sync, FTP need special requeriments, and most common options are very insecure (MS ftp, ProFTP, etc), so lest configure the most minimal and restricted posible, the PureFTP service software for Sybase sync databases.
Why and why not and where?
- Distributed data its the fashion and the rule those days.
- High availibility need real hardware, so Docker or VM are not viable.
- Sybase and ftp options offers the bi-directional feature.

feature | Best choices | others options | must or may change? |
---|---|---|---|
hardware | DELL T110 II | Docker/VM | Its good idea a more cheap like docker or VM its the best. |
Hard disk | SAS RAID 250Gb | nop | FTP sync implicts many I/O operations, we need good performance |
Net card | e1000 (1) | e1000 (1) | FTP sync implicts many I/O operations, we need good performance |
sistema operatvo | Devuan 1.0 | Debian 5 lenny | A non-systemd OS its mandatory, due the init < 2 process do not perturb the remaining services. |
ip4v | a VPN could be great | by-lan with DMZ? |
