Speed issues for restore 16 hours!

[briant]

Overall very happy with my Retrospect. 7.6.

 

However speed is a major in any restore scenario on my PC.

First to either do a system restore or find files restore, it takes for the first step about 8 hours for 250 Gb. And the second approximately the same time.

 

This used to be much less. And I think the problems started when I got some time ago the Continuous Backup option. I quickly relaised this was not for me, and tried to uninstall, but never received good advice from technical support. Nor did I find info in the Knolwedge base.

 

So my question why so long to do a restore (around 16 hours) I did it r3ecently and thanks God it worked. But 16 hours is too long. Earlier it might be 30 minutes.

 

What can I do what is wrong? Could i9t be remanats of Continuous back up wosening the performanced? Using Windows XP and backing up to a fixed hard drive D, and also using Netgear NAS Duo.

Not sure, what did the screen show most of the time?

[briant]

 

1) not responding in retrospect menu bar , same also in task manager - but I persisted becasue it was important and after 16 hours a reward. My files restored.

 

Re solutions

2)I am not sure Continuous Back up has been completely elinminated from my system. This could be a cause.

 

It would be good to eliminate this. It sill shows up under the automate menu - continous backup.

And sometimes the welcome dark black recatngle.

 

Of course other ideas would appreciate .

Forgot to answer prooperly.

 

What it is showing after 2 hours serached 1 of 124 sessions is the

message

 

Searching

Backup set name

Selecting 493,560 of 493,560 files

 

I am trying to restore one specific file to another location.

[briant]

Of course with this speed for restore, a miracle is necessary because it requires hardware and software to be capable of working error free over a period of 16 hours.

 

So could I receive some fast assistance please!

 

At least to begin with how to completelly eradicate all traces of Continuous Back up anywhere and everywhere in my system.

 

Thanks hopefully for a fast response.

The matching can be slow, but not hours typically.

 

What does the log say for Idle time and performance?

1) I ahave asked several times now. How to delete every instance of "Continuous Back up" and I am not getting an answer.

 

Please give me one ASAP.Or do you not know about this????

 

2) I dont think your response is very helpful. I have already stated matching is slow 8 hours plus. Much, much slowere than it used to be before I installed the Continuous Back up add.in.

 

So please take these as facts and give me some concrete suggestions for remedying this in addition to detailed steps on removing all traces of the CB. as per 1) above.

3) Typical log info for restoring

You're backing up from one local drive to another, and you're only getting 178MB/minute?! That may be your problem!

 

Are the drivers etc up to date? It also looks like your target backup set is storage on a NAS. Are you having any network performance issues?

Thanks for response. Performance is same when retrieving from an external USB.

Am convinced that CB is a partial culpit, but despite asking Robin a couple of times to supply info on total elimination of all traces. Zero response.

The RCB files are in a hidden directory normally on the C: disk. They are removed when you run the RCB uninstaller.

Thank you for pointing this out to me. I thought it was a technical support forum, as some support was being given.

 

Apologies for any "harm". In "defence" I was frustrated by partial info.

Brian,

 

And please accept my apology if I appeared condescending or reprimanding, because that wasn't my intent at all. I saw your frustration, which was the reason I responded.

 

If I had known the answers to your questions I would have answered your questions. Because I have no familiarity with the RCB product, I didn't want to speculate or provide misinformation.

 

Have a great weekend.

Hi, your problem could very well be related to your NAS's network performance with Retrospect together with the limitations of a USB-target.

 

Depending on the amount of matching that needs to be done and the amount and sizes of files involved. Local storage is much faster than a CIFS share (and with local storage I rather mean internal drives on your SATA, SCSI or SAS controller). And even though your ReadyNAS Duo is a nice machine, it's not very fast (I actually own one, so I have some experience with it).

 

To test this you would need to copy the NAS's contents to local storage and use those copied backup sets for a restore. And compare the results.

 

Also with a lot of external USB 2.0 drives they are not as fast in reality than they are on paper. Depending on how you connect to your USB drive write caching is also slower performing.

 

Something else: Are you running on a gigabit network? A slower 100Mbit network would slow you down even further.

 

So to sum it up, you seem to have two bottlenecks:

- NAS as a source

- USB-drive as a target

 

There are more variables, like how fast is your cpu, how much RAM is available, is compression and/or encryption used, etc.

 

So I don't think it's Continuos Backup in your case that's slowing down everything.

[briant]

Ramon thank you for your informed response.

 

I am a philosopher and not technically sleek!.

 

However, NAS restore speed is not a problwem. But earleir I have successfully used USB for back up and restore. And also local D drive same as my C drive. So this has nothing to do with networks or NAS.

 

My conclusions are;

A. Retrospect 7.6 some time over the last year has become significatly slower.

Or

B. Remants of Continuous Backup are undermining the normally speedy operations of Retrospect.

 

I belive the latter, installation was a mess (faulty links and instructions from technial support). In response to my question to technial support, I was referred to a Mirosoft cleanup utliity. Which needless to say did not clean it usp as from time to time remnants of the CB splash screen make their unwelcome appearance.

 

At the moment I think Retrospect when it comes to uninstallation of CB is in the same position as Norton AntiVirus a few years ago. They don't know how it can be completely, totally and irrevocably uninstaled.

 

Thanks once again Ramon.

 

If any user know how to "destroy" CB please let me know!.

For thorough Windows cleaning I sometimes use the free program CCleaner: http://www.ccleaner.com/

 

However this program is not without risks and you need to be a bit into Windows and such, as it can clean out your registry very well (use multiple passes). And do make a good image backup beforehand. Never needed that, but you never know.
