So many factors...apples, oranges, and grapefruit. Various affecters, including software level, may be involved. In particular, keep the following in mind (from my notes): Selective Backup, more overhead than Running a Selective Backup can be Archive expected to entail more overhead than a comparable Archive operation, in that more complex retention policies are involved in Backup policies than in Archive. Remember that Archive retention is based purely upon time, whereas Backup involves both time and versions decisions. File expiration candidates processing based upon versions (number of same file) is performed during client Backups (in contrast to time-based retention rules, which are processed during a later, separate Expiration). The more versions you keep, the more work the server is distracted with at Backup time. Richard Sims, BU
