Spideroak after Sugarsync… is disappointing

October 12, 2015 1 comment

Around four months ago, I moved from Sugarsync to Spideroak. I’d been using Sugarsync for over a year, and had been a keen advocate for the platform – indeed, I’d referred about 30 people to the service, and it had been my go-to cloud storage as that sector emerged, a few years ago.

However, although I loved the service and the app, one thing that concerned me was the security wasn’t up to my requirements – the fact that data might be encrypted using AWS standard techniques, but would still be accessible to any staff, any US federal agency that served a warrant (or didn’t) to the company, anyone who hacked my password (no 2FA), and anyone who found a vulnerability.

I wanted to store client data in the cloud, and feel some level of confidence that no-one else would be able to read or hack it, and if they did, then I had done everything I could have possibly done to protect it

So – I moved to Spideroak. Spideroak offer a similar service, but only you hold the keys to your data; no-one else can decrypt it. They also offered some convenient secure-sharing options that Sugarsync don’t, like password-protected ‘sharerooms’ where you can share a folder with a third party, and temporary download links you can send to share a file, but which expire after a few days. As a bonus, they offered massively more storage than Sugarsync, competing with Dropbox at the new standard of 1TB for $10/month.

The trouble with Spideroak is… everything else. The service is way clunkier for a number of reasons:

  • No mobile upload. With sugarsync, when reading documents or attachments in my email, I could file them away on my disk, there and then, by sending them to sugarsync and choosing the folder. Done! Finished! With Spideroak, the mobile client has no ability to upload! I’m back to flagging and emailing files to myself, to store away later when I’m back at my PC
  • Lack of mobile search. You can’t search for a file in the mobile client, unlike Sugarsync filename search, or full google-style search in Dropbox. While this is to be expected – you can’t index server-side when data is encrypted – there are acceptable partial solutions; such as storing a filename index on the mobile device, just to quickly jump to a file by typing its name.
  • Lack of mobile caching. If you access a file from your mobile device – and it is quite slow at doing this, sometimes unusably so – you’d expect it to cache recent files so that if you open then a second time, they’re just there, right?  Well – no. You have to download the file all over again, each time. The workaround is to ‘favourite’ the file first, so it’s downloaded and cached locally.
  • No collaboration. You can’t sync a folder with a colleague/friend. This is a fundamental capability of Dropbox, Sugarsync, Box, and almost every other service, but Spideroak’s security model seems to prevent this. I have a folder of all household documents shared with my wife’s laptop, and in the end, I simply logged her desktop sync client into my account.
    Yes, there are sharerooms, but they work with you as the master folder owner and others signing in on the web client; there’s no desktop sync
  • Slow, unpredictable sync. Spideroak uploads in groups of files that total a certain chunk size, which is interesting; they do explain this on their blog. What is more interesting, are the long periods where I see zero upload bandwidth on my bandwidth monitor, while the Spideroak client seems stuck at nn% of the upload. Why? Why isn’t it uploading?
  • Inability to prioritise/cancel uploads. Sit and wait is your only option
  • Unable to handle PST files. Outlook PST files are a pain, since they appear to break the Windows Volume Shadow Copy Service model that most backup/cloud storage apps use. Even Crashplan has issues with this. They all backup the whole file each time, even though not a single email has been added to the PST.
    With Spideroak, it means every time it checks for new files, it queues my five PST files totalling 10GB, and starts to upload them all over again from scratch! I get the impression other services do manage to do a diff and upload only the changed blocks – Crashplan ‘uploads’ (or block diff/syncs) in a few minutes, and Sugarsync never complained – but Spideroak tries to upload the entire 10GB each time. I have to remove those from the backup list
  • Slow to generate sharing links, unusable for new files. Spideroak has plenty of options to right-click a file and generate a 72-hour unique link to a file. But it’ll take 30-60 seconds to do it… you wait patiently for 20 seconds while the client struggles open (I have a mobile i7 laptop with 16GB RAM), then it tries to create the link, and then…. usually, nothing. Nothing, because for all the reasons above, I have a 30GB upload backlog, and the file I want to share probably isn’t synced. Particularly for new files you’ve just created, they’re added to the upload queue with no prioritisation possible (and will be grouped with other files and slowly uploaded in a batch), so it’s entirely useless for quickly uploading new files. I always end up using Dropbox.
  • Mystery downloads. I use Spideroak to sync my main content-creation laptop to a rarely-used convertible laptop and occasional access from my iPad. Nothing is created on these. So why do I see my bandwidth monitoring showing a download at 15Mbps, which TCPView identifies as going to the Spideroak service. What is it downloading? I guess it could be a program update, but I’ve not noticed any updates in the app, and it happens too often for my liking.

In comparison to Sugarsync, Spideroak feels generally more clunky all over – the app, the desktop client, the web service. You can expect much of this given the additional effort of encryption and key management across all this, but there are also many unexpected/uncontrollable behaviours that cause concern.

Sugarsync recently submitted a poll for new features, and client encryption was one of them. I suspect that it won’t make it – although privacy is gaining pace worldwide – and they will be faced with many of the performance/accessibility trade-offs that client encryption present. But if they do implement this, and get it right, I would happily jump back to their service, even for the much smaller storage allowances.

Virgin blocking Microsoft PPTP VPN?

May 17, 2010 2 comments

Interesting….

I’ve recently continued having problems with my Wife’s VPN, using PPTP VPN (the one you use by default in Windows). Rather than timing out during authentication, which was what I was getting when the router seemed to be blocking it, these days it seems to be rejecting it immediately. I’ve tried enabling VPN passthrough on my DD-WRT (ex-Virgin) router, and even connecting directly to the cable modem with no router, but I still get the same problem.

Then, occasionally, it works.

However, the interesting thing, is that the IT Admin for her work (a large UK university) says he’s had 4-5 other people also having this problem – all Virgin customers.

I doubt they’re deliberately blocking it – but perhaps something in their configuration isn’t letting PPTP through?

Canon MX860 – images appear washed out

June 30, 2009 Leave a comment

So, I’m now trying to use my Canon in anger, to scan some documents, and have found something that is actually making me angry.Canon MX860 Image Overcorrection Example

If you scan a colour document, it will perform some kind of optimisation that will wash out normal colours; it seems to apply contrast and brightening in one. I expect this is for archiving/smaller file size/better OCR performance. This didn’t seem so bad, but then it came to scanning some receipts and an MOT document. Anything with faint machine-type, became almost unreadable once scanned.

Some playing around, revealed that it IS capable of scanning with ‘normal’ contrast, but this is actually quite difficult. If I force it into photo mode, then it doesn’t apply the colour correction, and faint type is still visible.

However – that’s easier said than done. For example:
– If scanning to the MP Navigator software, it’ll automatically use the Document mode: even if I tell it to scan colour photo, and turn all correction off
– If scanning direct to memory card, then there are 4 options: Document (Platen), Photo (Platen), Document (ADF Simplex), Document (ADF Duplex). Of these, only Photo (Platen) gives the required results. Of course, that means there’s no ADF option for scanning without washed-out effects
– If scanning using other software (eg. MS Office Scanning), then there are two driver untitledoptions. The native one (Canon MX860 ser_xxxxx) gives the same washed-out appearance as before. The WIA Driver (Canon MX860 WIA, Windows-compatible) DOES keep the detail in the picture. However – THAT driver doesn’t support the ADF, or any other scanner features. Even playing around with MS Office Scanning, the best I can get is to scan one side, then feed the paper back in the other way around, and scan the other. So why pay for the duplex ADF?

I’ve phoned Canon Support – and a UK-based agent answered within 2 minutes, which was really impressive. However – they tell me there’s absolutely no way of changing the default settings on the scanner itself, so I’m restricted to this basic, manual method of scanning.

If you have any suggestions, please feel free to comment below.

Using a Canon MX860 with Checkpoint SecurRemote

June 17, 2009 Leave a comment

It’s been a while since I posted, but I thought I’d just mention this.

I’ve just bought a Canon MX860. So far, a beautiful all-in-one; the ability to print a photo contact sheet direct from the memory card, let you tick/check the photos you want on the paper sheet, and then scan it back in for it to analyse, and print out your order, is in my book, rather cool. I’ll still order my photos from Photobox because it’s cheaper and the ink may fade less, but still, rather cool.

However – the pain is that while it installed easily on one laptop, it didn’t on my main laptop. After a methodological step-through, it seemed that the culprit was Checkpoint SecurRemote. Although I had disconnected from our VPN, closed the System Tray app, and stopped the two Checkpoint Services, it still couldn’t detect the printer on my home network.

However – once I unbound the Checkpoint binding from the Wireless Network adapter I’m using in my home network – it picked it up. Evidentally, as long as Checkpoint has any influence at all, it’s enough to block whichever ports the printer uses.

I’ve since finished the printer configuration, and I’ve now re-enabled Checkpoint in all forms, and connected to the VPN, and they’re still talking… I haven’t rebooted to finish installation, so we’ll see what that brings.

Also note that I disabled a few other things, which MAY have had an influence: Symantec Firewall/AV, and VMWare Network bindings. They’re all back on as well, though.
