Does CA ARC SERVE Backup support Auxiliary Copy. Makes exact copies of backup tapes for redundancy. Copies are quicker to generate than actual backups. Copies can be kept onsite for disaster recovery.

Hi Jobby,

What version of CA ARCserve Backup are you using?

For R12 and up:
Use the data migration (Staging) feature to create a Clone/Auxilliary copy

How to set this up:

1. Modify the job you want to make a copy of and select the "staging" tab next to the "source" tab.
2. Select the target group for the first backup set ie. some tape drive or tape library (Your selections in "Destination" tab will now be the destination for the copy of the first backup set).
3. Check "enable staging" and set the media to "*" and the media pool prefix to the prefix of the target pools for the first set (not the copy) then click the "Policy" button.
4. Select the "Miscellaneous" tab (the first to tabs is used to set a delay fro the copy process)
5. Check all checkboxes and enter the media info in the textboxes. Select Append (a new set will be created every full set if using GFS jobs)
  "Media prefix" -> This is the prefix for the actual media name ie. prefix_mediapool_date
  "Media pool" -> ie LAN and if the job is GFS type, then 3 pools will be created with xxx_DLY, XXX_WLY, XXX_MLY.
6. Click ok and then start and follow the guide to submit the job

If you're shipping your copies to more than 1 offsite storage you should consider using media management? This can be a bit cryptic though, and sometimes its easier to just use specific prefixes to identify your tapes and their location ie. call you second copies for Clone_xxx or the likes

For R11.5.4 and down:
You will have to create a script/cmd-let that uses the tapecopy.exe from CA to create copies of your backup sets. This can be run as a post-job execution or as its own generic job.

Hope that answers your question.

Cheers
Daniel

It can...

We are using a virtual tapelibrary (an EMC clariion disk library emulating  an Adic scalar i2000) and a physcical (Adic scalar i500). First backup set goes to the disk library, 2nd copy is made of the 1st set and put on to tapes. You can then if you want a 3third copy, copy the tapes again to tapes so either a

D2T2T (Disk to Tape to Tape) or T2T (Tape to Tape) setup

Under the library/drive selection tabs, you just select the correct target destination for your data

The tape library selected under "Staging" will be used for the first copy, and the tape library selected under "Destination" will be used for the aux copy.

here's the screendumps requested (Create a new job or modify an existing):

CDL is our virtual tape library emulating a physcical ADIC i2000 tape library (1st copy)
ADIC is our physcical ADIC i500 tape library (2nd copy)

Hope this helps
