Use of mobile phone as a backup device
 

Background
I use a backup utlility to perform near real time encrypted backups of the documents folder on my work laptop; as soon as a file lock is released, the file is backed up (replicated). One such backup is written to a RAID1 NAS that lives in another building, and the other to a USB HDD plugged in to the laptop. Whenever I travel - which is frequently - the USB HDD is slipped in to my jacket pocket and ensures that if my laptop is stolen or fails, I can still easily conduct what I travelled to do so long as I can borrow another computer.

It struck me though that my HTC one X smartphone has 32GB storage of which 26GB is currently free - and the laptop backup only consumes 7GB. Given that I charge the telephone from the laptop anyway, it is tempting to use the HTC for document backup in place of the USB HDD.

Question
The HTC storage is NAND and therefore with finite number of write cycles, so am I asking for trouble using it as a frequently written backup device?

I have no idea what performance maintenance (think "TRIM") or life-enhancing software is installed. The smartphone needs to last another 18 months before it is replaced. No, I am not interested in a cloud solution; it is an answer to the question that I seek, please. :)

Many thanks as always,
TLXV

It will be fine.

Ta. :ok:

Remember that mobile phones get lost occasionally XV105, so make sure the info is encrypted if it's sensitive.

GG, do read the first line of the OP!

Oh dear, I'll stand quietly while you http://i1.ifrm.com/1889/52/emo/whipping.gif http://i1.ifrm.com/1889/52/emo/whipping.gif

:D

The late XV105,

Backup to your pet pigeon for all I care. Just don't break the redundancy rule .... anything important should be maintained at minimum in triplicate on different media (i.e. no point having three USB sticks or similar cheap-flash storage). And no, RAID whaever doesn't count as redundancy.... its one logical device.

Greetings, mixture!

For completeness having tried to keep my post simple.

Primary backup to Brand X RAID1 NAS that physically lives in a different building and is well hidden for good measure
Secondary backup to the USB HDD (now smartphone)
Tertiary backup to Brand Y RAID1 NAS that gets swapped for its sister (or brother, if you like) each time I go to the office (about once a month)

All encrypted.
The common weakpoint with the NAS devices is of course the disk controller on each, but this aside, I have five up to date copies of every file and seven copies if we are prepared to be up to a few weeks out of date.

Fine by me!

There's a good boy... <mixture throws XV105 a virtual doggy-biscuit stage left>

There's room for comment, but I won't, as it appears that you are doing a better job of it than the majority !

Feel free, please.
Always happy to learn!

One extra piece of info - whichever RAID1 NAS is at the office lives in a fire safe inside a secure server room!

Jeepers Creepers Lates,

Just what is all that info you've so securely kept???

You can tell us, your secrets are safe with us!

I think he's got Potus' codes to preserve.

Yes. Aside from the technical aspects of NAND-based backup, what are you going to do if someone steals your smartphone? Do you have the backup completely encrypted?

Mike B, do read the first line of the OP!

Deja-vu

Here's an encryption code for you. Answers in my thread on JB please.

BBC News - Has World War II carrier pigeon message been cracked?

Ah, I see TLXV complied with my suggestion to backup to his pet pigeon ! :cool:

Read "Double Cross". Ben Mcintyre. many many pigeons released by the Brits with attached messages were never intended to be read by the brits. .................they were there to confuse the Germans.
The Brits even used known incompetent "homing" pigeons, hoping that they would fly to German pigeon lofts,as the Germans were paranoid about British pigeons infecting their perfect pigeons.

Not a lot of people know that, you know.
