> 1PB of ZFS seems scary Why so?

I meant in one filesystem. No obvious way to construct a single zpool anywhere near that big. And if not one filesystem, curious how it would work in practice.

We currently allow 1.1 PB in a single "namespace" (zpool).

There are non-obvious ways to make a petabyte-sized zpool non-scary ... but even with those employed we still utilize raidz3 and have contingencies for rollbacks.

edit: for obvious reasons, that 1.1 PB number will grow by 50% in the very near future...

rsync.net aren't really competing with DropBox so I don't see the relevance. DropBox has multi-platform support on all major mobile and desktop platforms. They also have a GUI application that will "just work" for syncing your files off site. rsync.net is really UNIX only since the offering doesn't work particularly well when not combined with popular Linux/UNIX tools (e.g. rsync). On Windows you're left using FTP an…

Remember that "unix only" means all macs. That's significant and interesting (or at least, we think it is). You are correct that there is no mobile presence at all ... except for every single android phone. There is a "must be this tall to ride" bar at rsync.net and that's working very well for us and our customers.

I agree and disagree on Macs.

With Macs there are predominantly two "types" of users. Those who use a Mac because they want a UNIX machine that works well as a desktop/has a widely supported GUI, and then there are those who use Macs because they find them easier than Windows (due to the better consistency and less clutter).

I think rsync on OS X will widely appeal to this first group, but not appeal at all to the second group. As far as those people are concerned if it isn't in the store then it doesn't exist, and if it doesn't have a GUI it definitely doesn't exist.

As to Android you guys don't, as far as I know, offer an app? Maybe my information is out-of-date on that one.

I completely respect that you guys want to appeal to a certain demographic and there is something to be said for that. I was just pointing out above that rsync.net is niche and isn't "really" competing 1:1 with DropBox, Google Drive, or to a lesser extent One Drive.

Your prices remain quite impressive and I'm sure you do what you do very well.

That's not what OP said. The conversion to a free account and then back is not related to the refusal to refund his money. They temporarily took away paid features, but only because they botched his cancellation/refund request. When he pointed out their confusion, they corrected it. He didn't get a refund because they have a no refund policy.

But if they don't have a refund policy(which i understand), why would they botch it up/take away paid features anyway? Makes no sense.

It was neglect for sure, but I think it stemmed from poor communication and not malice. He requested that they cancel his premium service and refund him for the remaining duration. They cancelled the premium service, but neglected to tell him that he wouldn't get a refund. Also, this was during a time when a lot of people were trying to cancel, so I'm sure the customer service team was overloaded with this type of request.

The biggest benefit of Dropbox is the mobile app client support. On iOS, you see Dropbox and iCloud support, but rarely anything else.

When other sync services like Box and friends get more integration, I’ll gladly switch away since I would love some sort of encryption, which Dropbox, and Evernote damn you, appear unable or unwilling to implement.

Dropbox having good Linux support is a big reason I use them personally and professionally (both paid). But geez do they mess other things up. For example you can only share top level folders. We have to share with various outside parties and that limitation leads to a very cluttered file structure. The solution for multiple accounts is beyond annoying. The correct way of doing it how google does it - you provide how…

> Dropbox having good Linux support is a big reason I use them personally AeroFS (what I use), Bittorrent Sync and Syncthing (Golang, OSS) all support Linux (and Mac/Win) and are good alternatives.

While they all have desirable attributes, especially for individual usage, they are harder to cooperate with others. (By that I mean try to get friends and relatives to use them with you, when those folk aren't tech savvy and certainly don't have their own storage.)

> Dropbox competitors with encryption like Spideroak and Wuala Unless one doesn't really cares about security and wants encryption for the sake of having encryption, there's no way their implementations could be considered sufficient. Without audit you're just taking their word for it — which is exactly as when you take Dropbox's word that they won't peek at your data (unencrypted or possibly encrypted but one can't…

I don't know about SpiderOak but I totally trust Tarsnap. But agreed we have to trust the software companies/devs when using crypto. Not many people really trust Dropbox anymore to build client-side encryption themselves. But you could use a different program for encryption with dropbox as simple storage. That being said, you still have to trust the Dropbox binaries installed on your system as well. Security paranoia…

You can examine the source of Tarsnap, though, unlike Dropbox or Spideroak.

It's easy enough to jam enough disks into a rack with these 90disk 4u super micro jbods. The thing that always scared me (ESP with rsync) is how do you get performant metadata for a few billion files? Or even tens of millions.

And raidz3 resilver must be horrible at those densities!

Again. Just curious. Email at jmancuso@expandrive if you feel like chatting. I know we offer a similar product, but we are about to leave zfs for the above concerns. Wouldn't mind sending some business your way.

If you don't mind hosting yourself, Seafile is also open source and has really nice Mac/Windows/Linux/Android/iOS client apps. It also does delta syncs, which I don't believe ownCloud supports yet: http://seafile.com/en/download/ http://manual.seafile.com/

Thanks, that sounds even better. What's with the lack of delta syncs in all these systems? As far as I know, neither Google Drive nor OneDrive do it. Now you're saying ownCloud doesn't do it either. I didn't even think to look at it for oneCloud because obviously they'd support it. I consider it to be an essential feature, to the point that I won't bother with something that doesn't support it. I guess I'm unusual in…

I suspected I would get downvoted for not loving Dropbox. And I was right. Interesting.

FYI

rdiff is the reference implementation or first example of a utility written with librsync, which is the library that Dropbox used to build their "business".

Usage: rdiff [OPTIONS] signature [BASIS [SIGNATURE]] [OPTIONS] delta SIGNATURE [NEWFILE [DELTA]] [OPTIONS] patch BASIS [DELTA [NEWFILE]]

Options: -v, --verbose Trace internal processing -V, --version Show program version -?, --help Show this help message -s, --statistics Show performance statistics Delta-encoding options: -b, --block-size=BYTES Signature block size -S, --sum-size=BYTES Set signature strength --paranoia Verify all rolling checksums IO options: -I, --input-size=BYTES Input buffer size -O, --output-size=BYTES Output buffer size -z, --gzip[=LEVEL] gzip-compress deltas -i, --bzip2[=LEVEL] bzip2-compress deltas

Dropbox isn't ideal for backup at all. Look into Crashplan. Client-side encryption, unlimited versioning, never deletes files, and only $6/month for truly unlimited backup.

I'm already on the CrashPlan Family Plan. I love it. In all reality, I doubt I will get rid of Crashplan any time soon.

CrashPlan is great and encrypted at rest and transmission. But, I prefer services outside US
