I've read stories of people buying SanDisk branded flash cards then having the cards fail early in their life. Then they would call SanDisk to put in a warranty claim only to discover the card is a cheap knock-off, ie. not made by SanDisk. -- ubuntu-au mailing list ubuntu-au@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-au

Still cheaper and smaller than one hard disk, and you have the extra assurance that you are keeping more than one physical backup. You might also want to consider using Unison rather than grsync - it is a two-way synchronizer. I'm using it right now to sync my laptop & desktop's music directories.

Re: Flash memory as a backup for the Home directory
I think it is a great idea. When I run Ubuntu on my work notebook, an 8GB flash key is not only my home directory, but my root as well. Flash does wear out (though the onboard controller on the keys should manage a lot of that issue), and can fail like any other electronics. It is still early days, but I would imagine solid-state permanent storage is going to completely supplant rotating disks (but the disk manufacturers haven't given up quite yet) Regards, Martin martinvisse...@gmail.com On Tue, Mar 2, 2010 at 10:54 AM, Geoffrey wrote: > Having installed grsync I am about to buy an external memory to back up > my Ubuntu home directory. > For what I do on a PC I don't need much memory.

Flash memory as a backup for the Home directory
Having installed grsync I am about to buy an external memory to back up my Ubuntu home directory. For what I do on a PC I don't need much memory. At present there is 5.6 Gb on the HDD. This will increase but probably never exceed 20 Gb. The smallest and cheapest external disc drive is a 2.5" 250 Gb USB device costing about $85. However I have found a USB flash memory 'stick' with 32 Gb capacity for about $30 (source: e-Bay). It's from Hong Kong, is new but of unknown brand and quality. Being non-mechanical flash memory should have greater long term reliability than a 2.5" externala drive. I am already using a Verbatum 2 Gb flash memory which has synchronisation software (MS Windows) installed for a few XP My Documents files. It is a convenient way of continually updating backed-up data. Given my small memory requirement what do members think?
