I have tryed the restore now with no luck
i did the felxbackup -list with no luck
need help please

Hi Tom,
I've also been trying to work out how to use flexbackup. I even followed a how to (from Darrel ? Sorry, can't remember) on how to selectively restore, etc. but am having no luck. All that I can access on the tape is the /boot directory and nothing else.
I've since switched to using Taper (at least with Taper I can SEE what I am backing up and restoring -- selectively or otherwise).

will taper do an automated backup
Thanks
-
Hi Tom,
There's a how-to for doing just that.

Why don't you simply install my Restore Now contrib:
http://myezserver.com
/downloads
/mitel
/contrib
/restorenow-0.0.1/

I did and it didnt work not sure why

Try setting your block size to 64 (template 10Blocksize; hack /etc/flexbackup.conf). This sorted the 'list' problem for me. With the 10k default blocksize I could back up, but could I get anything back off the tape? Hell, no.
Not sure how or why it works, but it's worth a try.

I'm using an OnStream drive which only supports 32K block sizes. Once I set the necessary settings in taper, taper works beautifully so I'll be sticking to it -- much friendlier interface -- backup and restores are no brainers - just use the interface and forget about struggling with command line options and the like.

Hello everyone,
What is the command to set the blocksize to 64 in the flexbackup.conf maybe this will solve my problem also.

Paul van Dun

Temporarily change the "$blksize = 'N';" line in /etc/flexbackup.conf and run /sbin/e-smith/backup to try it out.
Once you have got the right blocksize (it all depends upon the hardware capabilities of your drive) then incorporate the value into the template "10Blocksize" so your temporary change does not get overwritten next time you change any of the tape backup settings from the server-manager.
The trouble with backup tape drives, so far as I can see, is that there is an aweful lot of trial-and-error involved in getting them working. There seems to be no central place to go to find out what settings are needed, which firmware revisions work with what OS version and which commands are likely to have problems working. So - fiddle on, and good luck.

The problem is solved, I've installed Darrel's Restorenow function and it works like a charm.
There's only one thing when I restored my user data all the permissions were set to data.data and they should be set to paul.paul
Is there a way of setting all the files in my user folder to the user paul.paul
At this time I issued the command chown paul.paul paul, is there a parameter to set all of it's files and subdirectories in one command.
Regards,
Paul van Dun
-
That'd be chown -R user:group files.
-
Thanks Dan,
it works, thank you !!!
-
Does anyone know where this how-to has gone?
-
Sorry, I meant the taper how-to as it does not appear to be on Darrells site anymore.
-
I hope its not out of line to post this.
Darrell found some issues with Taper and made the following post to dev info which would explain why you might not be able to find it on his site.
"I was just reviewing SME backup options and upon visitng the Taper web-site
(http://taper.sourceforge.net/) found the following:
[begin]
The current stable version does not support archives greater than 4gb (ie. it is 32 bit). Although the backups may appear to work, it will not restore because of overflow errors.
The Alpha version can be used, however, this is still under development and archive formats are likely to change between versions. [end]
I would suggest Mitel remove Taper from the iso, until this issue is resolved. Copy of this message will be forwarded to 'bugs' momentarily.

Hi DJ,
Yes, there is a long known 4GB limit with taper. I only ever use taper for systems that are not likely to have files growing beyond 4GB on backup (such as systems only used as a gateway or pop mail server). As long as the backup is below 4GB, I have no concerns with using taper. Hey, I run my business off an SME server and I use taper to store my files. Old stuff, I archive away on CDs and only current stuff sit on my server (hardly touch 1GB yet). So, 4GB, no sweat !
As I hoped all along, work is now being done to convert to 64bit which will overcome the 4GB issue. When that happens, the how-to would probably come back - possibly with a how-to for upgrading existing users to the new version of taper. Who knows, the new version might have automated restore facilities as well (which apparently is lacking in the current version).

Cool, cheers for that advice, might have gotten myself into BIG trouble!!!
HAve gotten everything working well with the restore now rpm, just took ages to do a restore (getting me very worried)
