The latest suggestion is for us to get an LT03 or LT04 drive. I just did a search around and found that the LT03 goes for upwards of £1100 GBP (and the LT04 even more). This seems excessive for a single server that has (at the moment a maximum of) about 150gb of data needing backup.
The plan was to get two tapes:
- Do a full backup once a week and incrementals for each day after that.
- Then swap the tapes at the end of each week and keep one off site.
I would have thought there was a cheaper/easier way to do this but this is the nth version of this backup plan and at this stage I don't know what to think.
I found a 250GB solid-state sata drive for £700 on Amazon. Oddly that's more than twice the cost per GB that you should pay for a USB pen drive - I definitely don't understand that!
As for ruggedness/reliability, flash beats tape hands down - there just is no comparison. Try placing a tape in washing machine, exposing it to direct sunlight for a few hours, or exposing to strong magnetic fields or repeated vibration.
The issue of limited writes makes flash ideal for backup. Flash is are also far less limited than tape.
