 |
|
Hi guys...
I was just wondering if, instead of putting a RAID1 solution (which I can't seem to be able to get to work), I could just do a nightly backup from one disk to the exact same one with something like:
| Code: | | # dd if=/dev/hda of=/dev/hdc |
Would it work??

Hmmm, maybe it would be a little long for 80G... What if I do that then a diff every night?
Any good ideas? |

i didn't do a raid1 because if i delete a file accidentally i would lose it.
for my MP3s i use just:
| Code: |
cp -Ruv /mnt/disks/songs/* /mnt/disks/songs_save/songs/ > $logfile
|
if i delete a file the file don't gets deleted on the second harddisk.
and every month i do a full backup.
i think this doesn't make sense in all uses. but for the MP3s it's good enough. |

True...
The thing is that datas I want to backup are fairly important (mail server, web server, etc) and I would like to make sure that I won't loose anything else more than one day...
And I'd like to be able to switch one disk to another if anothing goes wrong... |
