offsite backup
the idea of an offsite backup came up when two of a client’s servers almost got soaked when part of the office roof gave way during a strong storm.
i already setup a system where a backup of the databases and all important files from the desktops and laptops is done daily to a central file server. the next step would be to have a backup or a mirror of the data in the central file server located outside of the office.
the only major requirement for the hardware would be an equivalent or greater disk capacity for the offsite backup. i used an old 1.7ghz p4 with 256 meg ram, an adaptec serial ata raid 2410sa enclosure kit which, as of this writing, has been discontinued by adaptec but is still supported, and four (4) identical 320 gig sata drives. its a shame that adaptec has discontinued their enclosure series. i like them because i can change a busted hard drive without powering down the server. c’est la vie.
the offsite backup server was installed with linux — clark connect 4.1 sp1. rsync is used to perform the actual backup via the internet. i use ssh to give the setup a bit of a security blanket.
