Hello,
I require your opinion about my method.
I want to backup 500 GB of data from another company. Approximately 5 GB of data are changed daily.
We have a VPN 2Mbit/s (approximately 200 KB/s) between the two companies.
I have a computer (50GB, 256MBytes RAM) and an Ethernet hard disk (1 TB).
I use rsync XferMethod with parameters: --numeric-ids ; --perms ; --owner ; --group ; -D ; --links ; --hard-links ; --times ; --block-size=2048 ; --recursive
I developed this method:
1 – I install BackupPC on computer.
1.1 - “apt-get install backuppc rsync ssh sendmail”
2 – I put computer in another company.
3 – I mount Ethernet hard disk on computer and change backup location.
3.1 – “mount //192.168.400.2/backuppc /media/disk/backuppc/”
3.2 – “cp -Rf /var/lib/backuppc/ /media/disk/backuppc/”
3.3 – “chown –R backuppc:backuppc /media/disk/backuppc/”
3.4 – “ln -s /media/disk/backuppc/ /var/lib/backuppc/”
4 – I create private key (ssh) and I share it with servers to backup.
5 – I run a full backup.
6 – When full backup is completed…
7 – I put computer and Ethernet hard disk in my company.
8 – I configure options.
9 – Every night (only Monday (1), Tuesday (2), Wednesday (3), Thursday (4)) BackupPC run incremental backup across VPN.
10 – Every Friday BackupPC run full backup across VPN.
What do you think ?
And I hesitate to incremental levels 1 (for a differential backup) or incremental levels 1, 2, 3, 4 ??
Thanks a lot.
