Number of concurrent operations

[Eddie_Wilson]

I am running Backup Exec 10. On the configuration tab for a Backup-to-disk folder there is a field for specifying the number of concurrent operations ranging from 1 to 16. The help does explain what this is used for. Does this apply to the number of different jobs that can write to the folder at the same time or does this apply to the number of resources in the job that can write to the folder at the same time?

It's the number of different jobs (backup/restore) that can write to the folder at any 1 time.

Yes, John is correct its number of concurrent jobs but it hardly makes any difference because being the B2D as a target there could only be single I/O operation and thus you dont actually get the concurrent backups i

I disagree with Ashwin.
Our strategy involved a backup to disk to tape. We incorperate a 4 SATA drive RAID 0 for performance. We use RAID 0 (no redundancy) for performance only to get the backup windows down to about 2 hours on 22 servers. Using the concurrent feature for disk brought my original backup to disk backup down from 6 hours to 2.5. Hope this helps. The reason for the time saving is simple for us, some servers can backup faster than others so the disk array can handle more data than a single server.
Hope this helps.
