Crear proxy SOCKS 4 en linux ( tunel tunnel)
------
en la máquina de hace de proxy (a_inet.host.com) - la que sale a internet
- tener abierto el puerto 22 (ssh)
en el cliente (cliente.hola.com):
- ssh -D puerto_local user@a_inet.host.com
en el navegador (cliente.hola.com):
- poner proxy SOCKS: localhost:puerto_local
Crear tunel tunnel -- socat
socat TCP4-LISTEN:900 TCP4:192.168.1.9:30

-H, --hard-links preserve hard links
-l, --links When symlinks are encountered, recreate the symlink on the destination.
-o, --owner preserve owner (root only)
-p, --perms preserve permissions
-r, --recursive This tells rsync to copy directories recursively. See also --dirs (-d).
-t, --times preserve times
-v, --verbose increase verbosity
-z, --compress compress file data during the transfer

backuppc
------------
- necesita apache
- apt-get install backuppc rsync par2
- Mover a repositorio a disco USB y que monte solo en arranque
.. mover la carpeta y sustituir por enlace
- Definir usuario "root"
- http://localhost/
backuppc/
- Crear y restaurar un backup de windows con compressión y quitar duplicados
- Utilizar rsync
- Backup del propio servidor samba, SVN, webdav
- backup externo en 2ndo sitio
-.. crontab rsync -- creo que problemas con hardlinks
---> Utilizar este material ya está todo preparado

Rsync over SMB
rsync -rlptDv –modify-window=1 [source] [destination]
The “–modify-window” switch tells rsync to relax its timestamp comparison just enough for it to behave.
The remaining switches are useful for backing up to a NAS box, it’s essentially -a (archive mode) expanded, but without preserving ownership or groups (which doesn’t work well on the NAS.)
-a, --archive archive mode; same as -rlptgoD (no -H)
# comprobando contenidos en lugar de fecha/hora de modificación
rsync -av --checksum --dry-run --exclude 'lost+found' /path/source/* /destination/path/
