Back-story: I recently had a server crash on me and had to restore from Backup. I'm using an Iomega storcenter IX4-200D in raid 5. This has made me paranoid and wondering how the rest of the world does its backups.
1.Where and how is your backup data stored?
2.How to minimize file duplication?( I have users who copy lots of data into multiple folders thereby increasing the storage needs)
3.I'm using Cobian Backup for the file servers. ( I have no budget for purchasing backup solutions and frankly, i do not understand the price variations and licensing costs.) Anything to backup system state?
4.Offsite and cold backups.. Single large external Hard drive is acceptable?
Advise please.
