Backup process

mbriet

Hello
WE have a vmware infra
I test xcp-ng and xen orchestra

For the vmware backup WE use networker and datadomain with ddbosst si WE have source dedup

Do you have same process with xo backup
Do you have source dedup or not ?

Hi,

Sadly I understood only half of the post, but I can answer the last question, and the short answer is no (but we have compression). If you want dedup, you can use a NAS supporting dedup so it will be transparent for XO

Yes the datadomain (backup appliance) use dedup
But it will be the destination dedup so all segment are send yo the datadomain and After datadomain take the dedup
With source dedup the backup server take the dedup and After send the modify segment
So with with xo backup i think the backup take lot of much Time to process

I will configuré that and test on somes servers

We do a differential backup, so we only send the changed blocks, but for each disk. I suppose it's not as fast of whatever you used with VMware, but I can also assume it's a bit cheaper, right?

Sure
It was just a question
I know WE don't have same infra or feature IS not vmware but thé stack IS really good and interesting
And i Saw Comvault IS compatible with your stack and WE will replace networker with Comvault during next year
