I plan to upgrade a server containing forty 4 TB drives and replace these with larger drives. I'd like to repurpose the 4 TB drives for offline storage, using them essentially like tapes. I am looking for robust, easy to use (and hopefully <$500) software which I can use over a 1 Gb LAN to backup a >100 TB TrueNAS server to these externalized disks. This backup is for "last resort" scenarios if the primary and several secondary servers were to fail; I would be OK if I had some of the HDDs fail and lose partial data, but importantly, I could NOT have one or a few failed HDDs result in the loss of ALL data. I would envision using an eSATA or high speed USB dock, and plug in each bare drive as prompted. Ideally, I'd like the data stored on the HDDs to be in an industry standard format with directory structures retained in case the software failed and all I needed to do was mount the HDD and copy the data over to a new location (similar to unRAID).
Backup and recovery speeds are not hugely important. I'd prefer simple software instead of enterprise-grade level software with a cumbersome, complex feature set. All I want to do is run a program that incrementally copies the contents of my TrueNAS server to an external USB/eSATA drive and prompts me for the next drive when full, and similarly, restores the contents of the data set in similar fashion, skipping over any corrupted HDDs encountered to restore a partial data set. Linux is preferred over Windows, but reliability/ease of use is paramount.
Any suggestions are appreciated. THANKS much.
