Backup solution

[nelis]

RAID1 and 10 is far better than 5

RAID5 is the bastard child of "redundancy". Especially when you look at the amount of time required to rebuild a damaged disk in the array,the bigger the array the longer the time taken to repair and the higher the risk of secondary failures due to parity calculations/reads/writes when repairing

Oh makes sense. so you rather suggest a few raid 1 raid arrays. currently we have 4x raid 1 arrays. (2x2TB) in the backup server.
