What’s New

6

What’s New with VDP Advanced – Scale

Supports up to ~200 VMs per appliance

Up to 8TB of de-dup’d backup data capacity

•Deployed with 2TB

•Capacity can be added (up to 8TB total)

7

What’s New with VDP Advanced – Applications

Tier 1 Application Agents – App-level backup

for Microsoft Exchange and SQL Server

•Select individual databases for backup and restore

•Application-consistent backup and restore

•Higher level of de-duplication than image-level backup

8

What’s New with VDP Advanced – Upgrade

Upgrade from VDP to VDP Advanced

• In-place upgrade preserves backup data

•Capacity growth to VDP Advanced sizes

Backup and Maintenance Windows

Backup window

•Backup jobs should be scheduled in backup window

Maintenance window

•Scheduled integrity checks and garbage collection

• Integrity check can also be run manually

Checkpoints and Rollback

VDP Backup Technologies

Efficient backup mechanism

• vStorage API for Data Protection (VADP)

•Changed Block Tracking (CBT) – backup and restore

•Avamar variable-length segment size algorithm

•De-duplication across all VMs in VDP appliance

•SCSI hot-add avoids copying .vmdk across network

• Attaches .vmdk directly to appliance after snapshot

• Uses NBD if unable to utilize SCSI hot-add

45

Recommendations

46

Recommendations

Add DNS host record prior to deployment

Right-size VDP appliance at deployment

•Capacity can be added to VDP Advanced, not VDP

Use proper storage

•Many VDP support calls related to slow storage

Manage your snapshots

•Majority of VDP support calls related to snapshots

47

Recommendations

Monitor storage capacity

•Capacity warning issued at 80%

• Look for ways to lower capacity utilization <80%

•Health check limit at 95%

• Performance issues, new backup activities suspended

•Server read-only limit at 100%

• No new data allowed

Ideal steady-state capacity is 65-75%

48

Recommendations

Place VDP appliance close to protected VMs

•VDP utilizes SCSI hot-add

•Keep traffic of off network

Latest version of VMware Tools

Do not power-off the appliance

49

Recommendations

One partition per .vmdk file

•FLR does not support disks with multiple partitions

Time synchronization

• “Most recent request has been rejected by the server”

•VDP plug-in not showing

50

Recommendations

Avoid backups during maintenance window

•Restores can be performed any time

Make sure you are using latest version

•Example: Win 2008 R2, 2012 issue resolved

Always use fully qualified domain names
