Backup Design

Post by SGSA »

HI All,

We got following Setup

Site A.

2 x ESXi Servers and 1 x Vcenter Physical
1 x Veeam VM ( 2VCPU x 4GB RAM, Windows 2008 R2) -All in one Server simple backup design
Total 25 VM's
2 x ISCSI LUNS ( 1 TB) are attached to Veeam VM ( Through MS SCSI Initiator)

Site B -

1 x Esxi Server with local Storage

Questions:

1. Create 25 Backup Jobs or one Job?
2. What is the best Backup mode? (Reversed Incremental selected)
3. Active Full Backup Selected on Saturday and also backup set to everyday ?
4. Deduplication enable?
5. How many Restore Point? 3 is enough?
6. VM Retention days?
7. Enable both Guest Processing?

1. for sure 1 single job, so deduplication can be maximized
2. I suspect you are using site B for replication? Then backup methods in site A do not have nothing to do with replicas. Reversed saves you space on the iscsi luns, but are going to create much more I/O on those iscsi storage. Check if it can complete backups in a desired time
3. this depends on your business requirements, that we do not know
4. unless there is a specific need, always on
5-6. again, this is based on your business needs (and the available space on repository)
7. both? you mean guest processing and indexing? yes if there are windows VMs and you have to do quick file restores (indexing) and if there are vss complaint databases to be saved (active directory, exchange, sql) for the first option

Some reading on the raised questions:

1) How can I achieve best deduplication rates? Best way to structure jobs?
2) Choosing backup mode
3) How often do I need a full backup?
7) I’m wondering whether you have only Windows VMs or there are some Linux VMs, as well.

Thanks.

5-6. I would recommend storing at least 1-2 weeks of backups, but Luca is correct, check out your security policy and follow the recommendations ;)
