Best Practice using Staging Groups

[SebJS]

Hi,

I have approx 2TB of data I need to backup nightly to tape spread across approx 10 servers (one of which is very slow due to a huge amount of small files (10M+).

I have an 8TB NAS which I want to use as an incremental staging group which changes are backed up to each night.

Then I have 2x LTO4 drives in a group which I want to do a full backup for off site storage every night.

My theory was to do an incremental backup to storage group for speed and minimal load of server then a full backup to the tapes from the staging group but obviously I can only choose Full or incremental.

Can anyone advise me of the best practice for performing a daily incremental backup to my NAS then a full backup to my tape group. I have a 12 hour backup window and am running Arcserve 12.5.

Thanks for your help.

This question seems familiar. I answered this on some other forum so I'm not going to answer it again.

You will find that the ARCserve user community for the most part is interested in getting the answer to whatever question that happen to have. Perhaps someone else will answer but chances are slim.

What you want to achieve is a so called 'synthetic backup': running Full vs Incremental Backup operations to disk media and let the backup software create a full backup to tape media from the combined Full and Incremental back-up data. CA ARCServe cannot achieve this as there is no Synthetic Backup Option. The best you can get is using backup with deduplication to disk on a Full Daily backup basis combined with a Full copy to tape media. Another way to achieve less network utilization during backup hours is using CA ARCServe HA (the former XOSOft product). This way you replicate data from target servers to a central server which you then can backup locally. But this is a complete ackup approach.
