    • Spideroak both syncs AND backs up your files. Dropbox is not a backup service. Most importantly, Spideroak encrypts files on your computer before uploading them to their servers, which means only you can see your files and no one else. Dropbox doesn't do this, which means that Dropbox employees could access your files, which a much less private solution. Guest • Nov 2016 Disagree   Agree
    • Dropbox is not a good SpiderOak alternative because: 1) It doesn't offer end-to-end encryption and the privacy advantages that offers (that's a big deal), 2) it's emphasis is on sync, SpiderOak offers sync and backup. Dropbox has been reported to be an NSA surveillance target; SpiderOak has no such concerns because of its encryption system. Parts of SO are open source. JohnFastmanDec 2016 Disagree   Agree

    • If you just upload your files to Google Drive, two things happen: 1) you can sync them across different computers and access them from your Google/Gmail account, 2) they are stored on Google's servers in a way that Google can scan them and have access to their content. Spideroak allows you to backup AND sync your files, but in a way that your files and their contents are only accessible to you, no one else. JohnFastmanDec 2016 Disagree   Agree

    • ownCloud is a PARTIAL SpiderOak alternative. Through oC's client you can backup and sync files. Typically, oC is run on your own server. This means only your hard disk limits the storage space, and your files belong to you. But oC doesn't encrypt your files in the "zero-knowledge" way, which SpiderOak does. SO costs money; oC doesn't unless you get a hosted version. Use oC with Cryptomator to maximize privacy/security. JohnFastmanDec 2016 Disagree   Agree
  • MEGA icon


    You hold the security keys for 50 GB free storage, unlimited desktop sync bandwidth, and 10 GB per month of free bandwidth for sharing with other accounts.

    Freemium Mac Windows Linux Web Android ... iPhone Blackberry Android Tablet Windows Phone iPad Blackberry 10 Chrome Firefox

    • MEGA is similar to SpiderOak because it claims to encrypt your files locally before upload and not have the keys to decrypt them ("zero-knowledge"). However, since its inception, MEGA has been mired in various controversies and has had security flaws detected (since fixed). SO has enjoyed a solid reputation. Both MEGA and SO can become slow when dealing with large numbers of files (not necessarily large files). JohnFastmanDec 2016 Disagree   Agree

    • OneDrive is bundleware integrated into MS Windows. It seeks to "help" you by syncing your files, even every MS Office document you write by default. (Switch that off!) It's intrusive, and it seeks to upload unencrypted versions of your files to MS servers. SO is a privacy-oriented company that encrypts your files in a way that makes them accessible only to you. Both sync your files, but SO respects your privacy. There also isn't a Linux sync agent for OD. JohnFastmanDec 2016 Disagree   Agree

    Resilio Sync

    Resilient, fast and scalable file synchronization for enterprises and individuals.

    Freemium Mac Windows Linux Android iPhone ... Android Tablet BSD Windows Phone iPad Kindle Fire

    • Resilio sync is for syncing, not for backup; SpiderOak is for both. Also, SpiderOak encrypts files on your computer before they get uploaded, so it offers that much more privacy out of the box. Resilio Sync will sync files MUCH faster, but should not be relied on for backup because you need a computer running all the time to use it. Check out SyncThing as an open-source and more trustworthy alternative to Resilio Sync. JohnFastmanFeb 2017 Disagree   Agree

Files are encrypted on your computer and you hold the keys. Neither SO nor Tresorit can read your files. Tresorit is based in Switzerland, with stricter privacy laws. Both are Mac, Win and Linux friendly. JohnFastmanDec 2016 Disagree   Agree

SpiderOak Comments

Safe and rock solid, I didn't find anything better yet

Positive Comment by nicolaspilet
about SpiderOak Apr 2015

After a month using SpiderOak I am really happy. It is safe flexible and have the hive option trivial to use. The security aspect is really important to me and SpiderOak really deal carefully with that. I really encourage everybody to try. The only downside is the small free storage capacity compare to other (only 2GB). If you want to try, use this link in order to get 1 extra GB for free (3GB instead of the standard 2GB).


Back your stuff up if you use sync 1 Helpful

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

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 and 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?

about SpiderOak Jun 2011

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.

A decent backup tool - that's what this is.

It's not really an alternative to Dropbox as Dropbox is aimed at sync and this is aimed at backup. Yes it has a sync feature but the sync feature in comparison to Dropbix is terrible - in the event of conflicts, Spideroak just overwrote everything whereas Dropbox creates conflicted copies.

Currently I have the Pro version of Dropbox (as I sync all my data between work laptop and home PC) but I forsee when my need for syncing such large data disappears when I complete my studies, I'll move to Pro version of Spideroak.

SpiderOak & DropBox can also LAN-Sync

Positive Comment by em4020
about SpiderOak and SugarSync, Dropbox Jun 2011

In difference to SpiderOak or DropBox SugarSync can only Online-Folder-Sync, no LAN-Sync
I use virtual machines (VDMK, VHD) stored on quick USB3.0-connected SSD-harddisks.
If this SSD-disk is connected with my home-PC I want to synchronize certain folders about LAN-sync.
If this SSD-disk is not connected with my home-PC, I want to synchronize certain folders about internet.
With SpiderOak I can do a triangle-sync for folders: online-folderhome-pc-folderSSD-folder. Automatically the quickest accessable folder will be synced. With SugarSync at presence this is not possible, because you only can do online-folder-syncs.
I suggest to implement LAN-sync as a new and very useful feature for next SugarSync-versions.
With DropBox you theoretically can do LAN-syncs, but this function is not transparent enough to be sure, that it really works.
SpiderOak Download-Link for 3-7GB instead normally only 2GB:
Starts with 3GB instead 2GB, max. reachable 2 + 5x1GB = 7GB


FAR better than Dropbox

I found this app FAR better than Dropbox (annoying one folder limitation). I found it easy to set-up/customize, powerful yet straightforward and doing it's job with no problems.


I like both: DropBox (simple) and SpiderOak (more flexible)

Positive Comment by em4020
about SpiderOak and Dropbox Jun 2011

I like both: DropBox and SpiderOak, the totally simple DropBox and the more flexible SpiderOak
In DropBox you can only synchronize 1 directory with sub-directories: more simply, but it is a restriction.
With SpiderOak you can synchronize as many different local directories as you want. However, you must specify the directories, which you want to sync. And there are 2 separated steps to define: Backup and Sync. Maybe this is not so simple as in DropBox, but caused by the flexibility to choose freely definable folder pairs. If you want to synchronize a greater number of files/folders for free, it is necessary to use more than one synchronizing service simultaneously and to sign up with bonus registration links, which both services offer. I personally do not think, that setting SpiderOak up for the sync between computers is too difficult. It is a matter of 30 minutes to do the setup for 12 folders. Then you can use it for many years automatically in the background and you have no more work with it.
