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.
