Topic: Arkeia 4.2 & Sme and DDS4's not using total space

[adrian]

Does anyone out ther use Arkeia 4.2 on a Sme 5.6 (U5)

I would like to run full backups everynight (I know, Its a personal preference). But arkeia keeps asking for new tapes even though i have about 20 gig still available on the tape being used at the time.

Tape in use: DDS4 40gig

I have the Arkeia 4.2 manual page 117, but what a night mare. I installed this about 2 months ago and it's just complete pain in the rump.

You have to create 2 levels of backup just to get it to do a monday/friday backup.

How do i get it to do a full backup and keep the same tape in the unit.

I have checked the manual as i have it infront of me. I have been to the Arkeia site, a number of people seem to have found this problem but no soultion found.

A genuine call for help here can anyone point me in the right direction.

Thank You

Have you tried using the Arkeia contib from Shad Lords. It seems to do a good job.

It depends how you want to use Arkeia.
If you want to do it the sme/e-smith way then I assume you would use
arkeia-light-5.1.15-1.i386.rpm    
e-smith-arkeia-2.0-4.noarch.rpm    
arkjui-5.1.12.zip    

It will put a panel in server manager which allows you to setup Arkeia as a direct replacement for flexbackup which can be scheduled for daily backups

I'm actually using the earlier v4.2 Arkeia which used these rpms
e-smith-arkeia-1.1-1.noarch.rpm
arkeia-server-shareware-4.2.10-1.i386.rpm
arkeia-client-4.2.17-2.i386.rpm
arkeia-arkc-4.2.1-1.i386.rpm

You use the java applet to do restores from a Windows PC
jui-4.2.1-1.zip

These are probably at contribs.org as I see that Shad has recently rearranged his site and the old rpms do not appear to be there now.

DDS4 total tape capacity isn't 40GB, it is 20GB, and will hold up to 40GB of compressible data, which squashes to 20GB.  

If you are backing up files that are already compressed, you'll only get 20GB of them on the tape. This includes most graphics files, zip files, etc.

This may be why your tapes seem only half full.

Yup Tom your quite right.


HD: 36 gig available (Total)

HD: 24 gig used

HD: 10 gig free space available

Total used 69%

Question then an this wlways thorws me?

If i have 24 gig's of data and a twenty gig tape will this not compress it down to fit on this pirticular tape then?

Hence 40 gig compressed?

Cheers all

> Hence 40 gig compressed?
That's just marketing b******t. That assumes you get a 1:2 compress ratio, which in the real world never happens. JPGs, MP3s, ZIPs, etc can't be compressed any further, so you're lucky if you get 1:1.5. Just read the fineprint in the manual :-/

[adrian]

Hmm

Cheers Michiel cheers for pointing that out.

Thanks Ray, Tom, Michiel appreciate your help.

Hopefully  this will help others.

Two kinds of compression should be available: hardware compression via a jumper or dipswitch on your tape drive, and software compression through your backup software. Be sure one of them is turned on. I'd suggest using the hardware compression, but software will do if it is enabled.

24 gb of compressed files will not shrink down to 20gb, but text and program and data files will.
