Can you add to current media!?

[snowhawk]

Im not talking about adding to a media set...just the original media backup! If so...how?!

 

Basically I have been backing up to LTO-3 tapes but im not filling them totally so may want to add to them at a later date...can I do that without erasing the whole disk.

 

Also I have been doing this without compression on and sticking to under 400gb (as thats native limited on LTO tape) but it goes up to 800gb compressed...how does this effect how much goes onto one tape...I dont want to spill over into another tape in the media set.

 

Also how do you completely erase a disk!?

 

hope that makes sense

Nope; sorry. Not in the slightest.

How about one question at a time?!

 

1. Can you import catalog files from another engine without causing conflict?! (read somewhere is causes issues)

 

2. How do you erase an LTO disk because when I try to overwrite it it thinks its part of an old media set so won't start the backup...Is it the recycle feature?!

 

I apologise for the ramblings previously...not the best at explaining myself :confused2:

I can answer the first one: Yes, you can move *catalog* files from one Retrospect Engine computer to another. You just have to "locate" the catalog file in the Media Sets to find it.

 

 

It would only cause a conflict if you already had an identically-named Media Set in use on that engine machine.

1. Can you import catalog files from another engine without causing conflict?! (read somewhere is causes issues)

Yes, see the section of the Retrospect 8 Users Guide (!) entitled "Moving Retrospect" on page 238. The link to the Users Guide is here:

Retrospect 8 Users Guide

 

2. How do you erase an [color:red]LTO disk[/color] because when I try to overwrite it it thinks its part of an old media set so won't start the backup...Is it the recycle feature?!

Now I'm confused. I have never heard of an "LTO disk". LTO is a tape technology, and your original post discussed LTO-3 [color:red]tapes[/color]:

 

Basically I have been backing up to [color:red]LTO-3 tapes[/color]

If you are trying to overwrite an LTO-3 [color:red]tape[/color], your problem is that Retrospect tries very hard to protect your backed-up data, and makes it hard to overwrite/erase your backed up data.

 

The solution to that problem is to use the "Recycle" command, which resets the media set contents to zero (as indicated in the catalog and by putting a new header on the tape or disk media set). See page 237 of the Retrospect 8 Users Guide (!) at the link above.

 

If, in fact, your question remains:

 

Also how do you completely erase a disk!?

the answer is to use Apple's Disk Utility, which will blow away anything on a disk drive. See the "Erase" command.

 

To prevent you from doing something truly foolish, Apple's Disk Utility will not let you erase the Startup Volume from which your computer was booted. If you really want to erase your Startup Volume, you will need to boot from the Apple Install DVD or from an external drive.

Cheers Russ,

 

I shouldnt have gone back and forth with using disk and tape when explaining! It is LTO-3 Tapes im using

 

I do have another couple of questions

 

Firstly

 

In the manual it seems very complicated when explaining how to import catalogs done on another engine....now I did read a post of here saying you can click on the media sets page and locate that way!? will that work as I don't feel comfortable doing the code stuff if I dont have to.

Secondly

 

I have been backing up over the last week or so fine....I now want to check that I can restore before I completely wipe the drives ive been backing up from

 

When I click restore it starts to do it but stops saying incomplete...and its only done say 30gb of 250gb

 

I am running the console on another computer and im trying to restore to the computer with the engine on. Is there something im doing wrong for it not to work?!

 

Also I haven't used the client before is there any need for using that!? I was thinking it doesnt apply to the way im working

 

Thanks again for all the help

Ok, then I don't understand why you discussed "disks" in your problem statement.

I gave you the page of the Retrospect 8 manual describing how to do what you are trying to do. I suggest that you read that section of the manual.

I don't see any discussion of "code" in that thread for which you provided a link. Again, I provided you with a link to the Retrospect 8 manual and I even gave you the exact page on the manual that described what you need to do. There is no discussion of "code" in that section of the manual. Please explain what you mean by "code" and explain why you think that you need to write some code to do this simple task.

Like Dave, I don't have a clue what you are doing. You have not provided us with any specifics at all, and your problem statement seems to keep changing. Disk? Tape? Who knows.

 

I suggest, if you want some help from the rest of us users, that you provide a clear problem statement of what you are trying to do, exactly what you are doing, and your configuration.

 

Useful information would be:

 

(1) exact version of Retrospect 8 engine (8.x.x)

(2) exact version of Retrospect 8 console (8.x.x)

(3) version of Mac OS X on the Retrospect 8 engine computer (10.x.x) and flavor (Mac OS X server or non-server)

(4) version of Mac OS X on the Retrospect 8 console computer (10.x.x) and flavor (Mac OS X server or non-server.

 

Also I haven't used the client before is there any need for using that!? I was thinking it doesnt apply to the way im working

Again, I don't have clue about the way you are working. No information about whether you are trying to back up or restore computers on your LAN, etc. So there is no way to tell whether use of Retrospect client is appropriate for your configuration. You might want to read the Retrospect 8 manual a bit where it discusses use of Retrospect client.

 

Also, there is an implied "another engine" involved, which seems to imply that you have more than one copy of Retrospect 8 engine involved. You may be running into licensing issues that are affecting what you are trying to do (whatever that is). Please also provide information about what license version of Retrospect 8 you are running.

 

Once we get a clear picture of your configuration and what you are trying to do, perhaps one of us might be able to help.

Ok...

 

So the importing of the catalog it says in the user guide to replace certain files on the new computer then do something in terminal (thats the bit I ment about the code)

 

I thought you may be able to just go to locate in the media sets tab and find the old catalog having put them on the computer.

 

Right as for backups/restores

 

The engine = Where do I find the information about that!?

The console = Version 8.1 (build 626)

 

Mac OS X with engine = 10.5.8

Mac OS X with console = As above

 

I have tried using the console on the engines comp too

 

Both computers are on server

 

As for the way im working

 

I have a load of external harddrives which im having to backup to LTO3 tapes via retrospect

 

The backing up says its successful but the restore hangs on retrieving tape blah blah having done around 40gb.

 

Please don't take that tone with me....im completely new to all this so im a little out my depth. Im trying the best I can and im grateful for any help thrown my way

 

I should point out im still using the trial version...would that have anything to do with it

Rich, don't be so overly senstive. I was just trying to help. We are just users in this user-to-user support forum. We don't get paid for this.

 

There may just be a communication problem here in that I'm having a hard time getting the necessary information from you, and you think I have a "tone" when I'm just trying to get basic information so I can figure out what is happening and how to help you.

 

I suggest that you contact EMC Retrospect support, and they may be able to help you. Here is the contact information:

it says in the user guide to replace certain files on the new computer then do something in terminal

 

The ownership change for files you bring in from another location can also be done using the venerable BatChmod:

 

ttp://www.versiontracker.com/dyn/moreinfo/macosx/12057

 

- Select the folder (even though the button says "File...")

 

- Select "root" from the "Owner" popup menu

- Check all three boxes under "Owner"

 

- Select "admin" from the "Group" popup menu

- Check "R" and "X" under "Group

 

- Check "R" and "X" under "Everyone

 

- Check "Change ownership and privileges"

- Check "Apply to enclosed folders and files"

- Check "Clear Leopard's extra permissions"

 

- Click "Apply" button and enter your administrator password when asked.
