Secure online backup

[nwpmikey]

Hi guys..

Just a quick question..
I work in a prepress department and we are now looking into secure online backups.. because work hadnt backed up properly since end of dec2008 and our backup drive went bang after a power a spike (i am now running via a UPS and surge protection system, Took me a while to convince bosses to get these just incase) we lost everything from this year.. i managed to get some of it back but not all..

Could anyone who has or does use secure online backups please let me know who you use and the good and bad points..

At the moment i am trialing DIINO but am going to trial others also..

We curently backup to AIT Tape but have found some of these have become corrupt....
And i have now got a raid system in also to back up to
Many Thanks

Mike

I prefer a linux based NAS server with Raid 0 or 5

hi.. i had actually suggested something along these lines to managemet but was told they want something offsite incase of fire or break in....

actually, leave another machine at home and do automatically backup job will solve this problem

Raid 0 (striping) is not a good solution for a back-up system! As datas are written alternatively on the two disks, Raid 0 gives fast reading/writing... but absolutely no safety, and even more risks: using 2 disks gives you twice more risks of a disk-crash... and if one disk crashes, you have only half of the datas in the other disk, and in fact all the datas are lost!

For a 2 disks system, prefer Raid 1 (mirroring): each disk is an exact mirror of the other one, so if one disk crashes, datas are still available in the other disk.

my mistake, you are right, should be raid 1, I m using raid 5 now because the we got more than 8 disks on data server.
