Tried to run the client installer (to update older client) on 4 different machines: error the installation could not complete.

Tried to uninstall first, then reinstall, same thing.

But after, in every case, it appears that it was updated, not sure why the error.

I use this everyday. I have 2 networks of users backing up. They backup logged in OR logged out. I like the Proactive backup and on the server side I like the ability to backup to many small files. Their support is very good. While there are problems with any software they have been excellent to work with. Keep up the good work guys.

6.3.029 Sonic branded client is available here:


According to Retrospect on Twitter, major work is underway. A screen shot of the new client (albeit a Windows image) is offered.

After over a decade of using Retrospect -- I cannot ever recommend Retrospect to anyone, for any purpose:
- Retrospect is buggy and bloated, often freezes client machines
- Retrospect is expensive, and upgrades are outrageous
- Many legacy backup devices no longer supported

The ugly truth is that often times, Retrospect will FAIL TO SUCCESSFULLY RESTORE a file. That is the true test of any backup/archive solution. Unless a sysadmin can KNOW that a solution is reliable -- it is dangerous to ever trust it.

When it really counts -- Retrospect cannot be trusted.

EMC/Dantz I have tried to engage at conventions have been dismissive and unhelpful in solutions for recovery failures. Although we have spent many hundreds of dollars on Retrospect, we've ditched it entirely, and moved on to a much better solution -- ChronoSync.

The 6.2.234 update stoped Retrospect from seeing the client on the first 2 Macs I installed it on. I had to downgrade to 6.1.130 to get the clients talking again.

I run into this problem in older versions too. What usually works for me is turning off the client (hold Command and click the Off radio button in the client) and then turning it back on. Other things that have helped are rebooting the server, rebooting the client, and rebooting the network switch. It's a royal pain that the client network connections are so fragile.


Here's what always works for me, no server restart required:

In Retrospect, remove the client from the Client list. It'll ask if you're sure you want to forget that client. Click OK.

Click Network. Most likely it will not list the new client, so you have to add it manually. Simply click 'Add by address' and type in the client's IP address. Voila.

The only pain is you have to reset the Volumes.


I don't type in IP addresses manually because they change from time time (DHCP). If you have static IP's for each computer, go for it; that would be a lot more reliable than Retrospect's method of finding clients.

Goodbye old friend.

I have been a retrospect user since Noah built the ark but it is patently obvious that EMC2 or whatever they call themselves this week, has lost the plot, lost the initiative, dropped the ball and have turned a sturdy wonderful product into a dinosaur. I have realised lately that with hard drives becoming cheaper and more reliable that to pursue either a raid policy or a daily cloning to another hard drive is the way to go.
Thank you for the support you have given in the (distant) past but I fear we are to say goodbye.

Retrospect is the only option if you want to prerve older versions of your files while also backing up the newer ones ("incremental backup", or "progressive backup"). For me, that has saved me twice a lot of time when in earlier backups some files turned out to be corrupted.

It works well with Panther (10.3.7), and I use it for both MO-drives and CD-RW. I have not encountered a single problem, and I make daily backups.

not the only option. most incremental backup utilities have archival options. i use synk 4.1 for exactly that.

TOTALLY DOESN"T WORK AND F*@$s UP your mac....i hate Dantz....can't delete it from your computer either....such irony for trying to back up your computer when all it does is make EVERYTHING buggy.

Are you sure you read the instructions??? While is not nearly as user friendly as Carbon Copy Cloner, it IS much more configurable, and maintains a chronology of incremental backups. As far as uninstalling it, I have done so in the past, and it came off fine. What issues are you having?

He probably dloaded it using Limewire and now somehow configured one or the other to interfere with each other.

Either that, or it's a competitor.

Fact is, I've been using Retrospect since the early days and manage to backup over 300 computers via the network. Been doing so for many years now. I've tried other programs (even PC ones) and for ease of use and reliability, Retrospect cannot be beat.
