Problem Statement: Having 80GB external disk and using JFileSync to take backup. Now it is going to full soon. Also system hard disk.
When data is increasing, JFileSync is taking too much time to compare and to perform sync after that.
Solution 1:
Buy 1.5 TB internal hard disk. Install as secondary disk.
Buy 1.5 TB USB hard disk
Use backup software to take backup.
Problems: backup time is very high. difficult to maintain over period of time.
Advantages: Internal disk is safe with big tower system. We can store external USB in safe place.
Solution 2:
Buy: D-Link DNS-321 Network Attached Storage Enclosure – 2-Bay SATA, RAID 0/1 from compusa
Buy: Seagate 1.5TB SATA Barracuda 7200.11 Internal Hard Drive – 2-Pack from Dell
Setup RAID. Life will be cool.
Problems:
1. In case of theft, we may lose whole system.
2. We need to configure how to take backup if we add second disk after n days.
3. We need to protect it on internet or add to USB
