Looks like I struck a chord!
I mentioned that Carbonite is unlimited storage but it seems that was missed. It's unlimited. I have about 170GB on it. About half is photos. One thing that Carbonite does, which I did not want to get into detail previously, is by default erase your files if they no longer exist after 30 days. There is a "Freeze Your Backup" option, but I've not used it so I'm not familiar with it. Erasing after a month is fine with me because I'm constantly reorganizing my folders and, I have that second HD for a permanent backup.

There is a "Freeze Your Backup" option, but I've not used it That is quite important, too. On another note: their security page http://www.carbonite.com/en/online-backup-software/secure-data-backup states that the data is encrypted before transfer and remain encrypted on their servers. The security paper reads: "To further protect our customer’s data, encryption keys are never stored with customer data." Which can be read as "the keys are backed up to the provider and hopefully kept separately from customer data." Hence a user keen on privacy would probably have to encrypt data locally before running the proprietary sw for backup, wouldn't she? That could prove unbearable with 300 GB+ volume of data... Some linux friendly solution with on-the-fly encryption per single file using keys generated and stored transparently and kept only at the user's computer would be great, imho.

Delete after erase? That leaves you vulnerable to an unnoticed accidental erasure, surely very common. How long would it take you to notice that one rarely accessed but valuable photo had been erased?
To protect against this, multiple backups must be retained. -------------------------- Sent using BlackBerry ----- Original Message ----- From: Paul Verizzo <[hidden email]> To: [hidden email] <[hidden email]> Sent: Thu Feb 24 02:45:50 2011 Subject: [Digikam-users] More on backup Looks like I struck a chord!

Hmm, 'unlimited', from the website:- With your Carbonite subscription you get as much space as you need for your backup. However, for exceptionally large backups – 200GB or more – backup speed will slow noticeably after the first 200GBs have been backed up. I have about 100GB of jpegs and 240GB of raw files so I'll stick with backing up to multiple HDDs, at least one off site at all times, it's quicker and cheaper.

What connection do you (the ones that use external HDDs) use? USB? Great topic. Thanks. O On Wed, Feb 23, 2011 at 11:06 AM, Milan Knížek <[hidden email]> wrote:

One can use encfs, that is fuse based (so simple users can mount/umount encrypted dirs), and encrypts on the fly all the files in a directory: http://www.arg0.net/encfs It's really easy to use, and there are out there some service menus for dolphin or konqueror to make easier to mount/umount an encrypted directory. regards gerlos -- "Life is pretty simple: You do some stuff.

I have actually been using encfs for a few years now to encrypt completely my home directory. I would prefer to have users on local network with uncomplicated access to the NFS export, so I may end up with some automatic mounting of the encfs share during startup w/o need of a manually entered password. This would create some unnecessary cpu load for my light-weight server, especially when considering that I do not need encryption on local network. Well, I need to think it through a bit and possibly test.

A couple of other people said they keep the images on the card for a while after downloading. My problem with this is that it requires great care not to mix up cards that have been downloaded with cards that haven't.
I prefer to download and erase immediately while I'm sure of the status of the card. Otherwise I risk erasing a card I haven't downloaded yet, or at least downloading duplicate images. I can see that having my only copy on a laptop is risky, especially while travelling, but this sounds riskier, for the disorganised, at least. -------------------------- Sent using BlackBerry ----- Original Message ----- From: Julien T <[hidden email]> To: digiKam - Home Manage your photographs as a professional with the power of open source <[hidden email]> Sent: Tue Mar 01 17:28:22 2011 Subject: [Digikam-users] Re: More on backup 2011/2/23, David Vincent-Jones <[hidden email]>: > My experience with off-site backups was not so positive.

I am beginning to worry about only having my photos stored on one planet. What
with these eruptions on the Sun and various earthquakes, tsanamis and tornados if anything happened to the Earth I would lose them all. Ideally I would like to copy them to some off-planet storage like underground on the Moon perhaps. So come on NASA, there's another commercial application of space technology I bet you never thought of. _______________________________________________ Digikam-users mailing list [hidden email] https://mail.kde.org/mailman/listinfo/digikam-users |

Why not just transmit them by radio in to space? Then you can "listen"
to them again whenever you need... 2011/3/1 Graham Dicker <[hidden email]>: > I am beginning to worry about only having my photos stored on one planet.

However, if the planet fails, your pictures will probably be a negligible problem in the context... If you don't expect to be off the planet when it happens that is, and in that case I assume you have also solved your backup problem? -- Johnny _______________________________________________ Digikam-users mailing list [hidden email] https://mail.kde.org/mailman/listinfo/digikam-users |

I'm an old crank, and even though I enjoyed the off topic discussion
of how to backup photos, since it has devolved into jokes, I'm less than thrilled. It seems people trying to be funny on line only works for the ones that are really good at it, and rarely on a topic discussion list. Yeah I know, I'm an old cranky fellow - but how about you guys take your jokes to private tweets or something.. /j On Tue, Mar 1, 2011 at 9:42 AM, Johnny <[hidden email]> wrote: > Graham Dicker <[hidden email]> writes: > >> I am beginning to worry about only having my photos stored on one planet.

Yes, it was a jokingly style to digress about planets, whoever Graham did point out an important and basic consideration in devising a back-up strategy, which pretty much sums up the discussion; probabilities and consequences, which is a function of redundancy and diversification. This is the core of why backups are done. Suggestions have involved: - Single backup as well as dual back-ups on same type of media (redundancy) - Same location vs. different locations; in the cloud or at a friends place (separation), - Different storage media such as optical vs. magnetical (diversification) These are all considerations one should contemplate in choosing a back-up strategy. What failures do you expect? What safety do you want to achieve and at what cost/hassle? What level of functional and physical separation is necessary to achieve those goals? > Yeah I know, I'm an old cranky fellow - but how about you guys take > your jokes to private tweets or something.. /j Backups are a pretty boring topic, and most don't bother until it's too late (as some have exemplified). To just make *any* backup puts you pretty much safe, but things can still go wrong, so it is useful to consider *why* and *how* to proceed, instead of mechanically doing it because "it is good". Apologies for any offence caused by using an informal style of writing, that was certainly not the intention. -- Johnny _______________________________________________ Digikam-users mailing list [hidden email] https://mail.kde.org/mailman/listinfo/digikam-users |

I manage a list with 1500 subscribers (no idea how that compares to this one) so I am maybe a bit sensitive about off-topic stuff. (I'm painfully aware that this too is off-topic. But hopefully this post will clarify that I'm not upset or offended or even anything more than bemused and so will end further discussion about my perhaps errant earlier post.) I definitely don't want people posting jokes, favorite recipes or internet sites, forwards, etc., to that list as it is strictly a community announcements/trade thing. And again, I did enjoy the discussion of photo storage as that probably should concern us all and I'm about to buy some kind of solution. (additional to what I'm already using.) cheers, JD _______________________________________________ Digikam-users mailing list [hidden email] https://mail.kde.org/mailman/listinfo/digikam-users |
