I just read a newspaper article about house fires, and it struck me that one of the things that might well be lost in such a mishap would be my financial records etc that are stored on my computer.
Having just lived though this example where my office was lost, offsite backups are critical.
No solution but additional questions and thoughts:
I never managed to get reliably into a remote computer (*). Seems I am too stupid for this.
i never thrust computers who are open to the internet for incoming connections. remember the last couple of weeks?month? with the ssh security problems!
So what I do, is doing backups on alternating external disks, which I then physically bring to another place like once a week. I will never have a absolutely recent backup, but at least I will not lose everything...
one of the most secure solutions in my opinion, even if you lose a little bit of work. i do the same with always complete dd backup of the hd/sdd's. booting from a prepaired external stick or at some computers a second (old) drive only inside the computer for this purpose, which will do the backup without user interruption to a bz2 image on external drive. very simple, no use for special software, only some shell scripts. of course for the time of the backup the "normal" system is not usable. periodically with zeroing the not used parts of the disk, periodically without. bring this external drive to a other location. best thing here is bring the backup back and in an hour or so the exact state of the date of the backup is back on my computers. .... and of course i tested bringing back the data to make sure the backups are good. a backup without trying to recover is a bad idea at all. could be lead in total data loss. personally i have had a bad data-cable and for this once made bad backups. so testing if everything with the backup is ok is something who must be done. bad thing of such backups are if you like to only recover some files, it will make some more work. need some drive to extract first, then mount. and with the increasing amount of data you like to store it will be worse. here i backup mostly ssd's up to 2tb most only half full. bz2 files are much smaller. it takes between 30 minutes an 90 minutes. if you have hdd' (only some older pc's with it left) it take some hours. simoN -- www.becherer.de
