Back your stuff up if you use sync

Negative Comment by plasbot about SpiderOak Nov 2013

Use something like todo-backup to backup your files if you setup syncs using Spider-oak. Spider-oak syncing is slow as molasses. I signed up for 100 gigs and synced up 'my documents' across 3 computers. I installed a new hard drive on my laptop and restored the sync. Of course it took days to sync up, in fact it's still working on it, I'm used to that slowness already. But over 2 days Spideroak systematically deleted 62036 files and 7150 folders, because the laptop didn't have all the files and folders, it decided that I must have deleted everything.

I went into the recycle bin in Spideroak to look for my files and folders, they were there, but there is no way to sort by date deleted column. At the very least, you should have a way to sort by date deleted to make recovering from these disasters not take a full week of plodding through each and ever folder and subfolder.

Luckily I used another product to backup and it was easy to restore the files. Using spideroak recycle bin would have been a mind-numbingly slow and cumbersome process. The warning about 'exact file structure' when restoring a sync needs to be clarified, why can't it just say 'if you have some folders and files missing on this new pc we are going to delete them from all your other pc's"

Easy, nice and secured

Positive Comment by square about SpiderOak Oct 2011

I've been using SpiderOak for few month, and I find it really easy to backup and sync all my files. All is encrypted and very secure. It's also very easy to backup your critical files : configure the files you want to backup and then one button click !

I was using Dropbox but I will let it down now. I'll keep my SugarSync for files that don't need high level of security. But for the most important documents, I'll use SpiderOak.


Okay but not amazing...

Comment by RoastedBanana about SpiderOak Also mentioning: Dropbox Sep 2011

I mean, I signed up simply 'cos I liked its ability to encrypt data. However, what happened was that everytime I tried to upload data, every file was stuck on finalizing. I even tried running a few commands and other fixes suggested in certain forum threads but those simply wiped out everything I'd uploaded. I ran out of patience when a number of files later, the issue was still around.

I didn't contact the help support btw, 'cos I was just simply looking around and it didn't seem worth my time to go through a ton of steps just for some files. And from the forums, the tech support didn't seem too responsive anyways.

In the end, I'm going back to Dropbox. After all, what use are those touted features if you can't even upload a file?


Spideroak is a great service.

Positive Comment by dnel about SpiderOak Mar 2011

Total encryption, easy to use software, decent pricing: all makes Spideroak a great service.


SpiderOak is mostly perfect software in comparison with Dropbox or SugarSync. It allows select folders to share and filter files by extension. SpiderOak can sync more faster if you exclude *.tmp, *.log, desktop.ini and other useless files. So if you need syncronize not huge amount of data SpiderOak is excelent solution, otherwise I reccomend SugarSync. It allows to use 5 gb for free from the box. By default SpiderOak allows to use 2 Gb of free space. If you want 1 Gb more space, just use a referral link.
