Default backup schedule and retention policy
By default, all infrastructure components are protected by DPM with the following schedule.
Table 15. Backup
Backup Policy for: Target Backup Frequency Retention
Infrastructure VMs

Azure: Once per week; Sunday 8pm

Infrastructure databases
Disk
Azure Backup (if opted in)
Disk: Every four hours
Azure: Daily (10:00 PM)
Disk: 5 days

NOTE: While these are the default settings, we recommend that you use the DPM Create Recovery Point Now option to back up
a VM’s databases before and after you make any conguration change.
By default, all tenant VMs are protected with the following schedule.
Table 16. Tenant VM backup schedule
Target Backup Frequency Retention
Disk Daily (10:00 PM) 7 days
Azure Backup (if opted in) Daily (6:00 AM) 20 days
You can change the day of backup or time of day if you need to. If you change the schedule, make sure that you at least maintain the
following backup frequency:
• For infrastructure VMs: once a week backup with a two-week retention period
• For databases: once every four hours backup with a ve-day retention period.
NOTE
: Dell recommends that you do not change the number of recovery points because this will impact storage calculations.
DPM does not back up the DPM database. Instead, the DPM database is backed up through the Windows DPMDBBackup Task Scheduler
job. The backup frequency is every 4 hours, and retention period is one day. The following table includes information about the DPM server
database.
Table 17. DPM database
DPM Server Name SQL Server Instance Name Database Name
<Prex>DMPO# MSDPMDB DPMDB_<Prex>DPMO#
NOTE: DPM is used to back up the system databases in the MSDPMDB instance.
