Hey @Tim_G ,

I would not risk to go back in time, i feel my current place is the best fit, but if circumstances are different i'd love to go astro physicist.

Welcome @vmnomad

Thank you all for the valuable details, was never considered before, i will work on the backup concept including replication to another site, Kind regards.

@Dashrender siad:

RAID 5? are those on SSDs?

it is going to be standard 4TB 3.5" SATA, which should be fast enough to receive the daily backup, and not that much expensive.

@Dashrender said

You have two VDP appliances in the same location? How come?

as i'm trying to create a duplicate of the backup disks, so each week one set will be offsite whilst the other attached and getting the backup, if i use one VDP, i can attach the disks only on the first setup time of the VDP appliance, i can attach existing disks, but i can not detach, the only way is by creating two VDP appliances, each is stored on separate RAID set.

@Dashrender said:

I would not be happy about moving a RAID 5 set of drives around every week. Will it work? Sure probably for a while, but man that's a lot of stress on those drives? I'd move up to a RAID 10 or at least RAID 6.
have you considered a tape solution instead? Does VDP support tape?

i think considering RAID6 would be good for two disk failure fault-tolerance, no VDP does not support tape drives, http://blogs.vmware.com/vsphere/2014/02/vdp-backup-to-tape.html , and if it does, +8TB of tape storage is very big expense ,

RAID sets are not to be ever moved. Ever. If someone suggests this, you have problems. RAID is not meant to be used that way, ever. While technically on paper you might make it sound almost rational, in real life this is totally unacceptable. This would be a "once in an array lifetime" event because the chassis died. You would never do this intentionally. This is a misunderstanding of the goals and physical implementations of RAID systems.

I think it does make sense to recalculate the overall time and money cost and do something about using offsite over internet replication instead, and push harder on the my management to agree with what is required.

@Dashrender said:

Technically, since you're using iSCSI that is not NAS, it's SAN. Why are you using iSCSI instead of CIFS/SMB or NFS?

I think I wrongly mentioned the product name, it's QNAP TurboNAS, https://www.qnap.com/i/en/product/model.php?II=203, Will attach with iSCSI instead as it have a little bit higher performance than CIFS/NFS with vSphere.

Hi @scottalanmiller , Thanks for your reply,
I'm not planning to replicate the backups over network or internet to another VDP appliance, my daily backup amount is huge to be transferred over internet, even taking the full day to transfer on full bandwidth of 100Mbps it won't finish uploading.
As i have a secure store (physical storage place far from main office) i'm planning to send and retrieve hard disks physically on weekly basis, what i was thinking so far as follows, but not sure if it is the best way:

• on the QNAP NAS have two configuration of RAID5 and hosting iSCSI data store, connected as BackupStore01, BackupStore02
• each store to have a copy of two VDP appliance, VDP01, VDP02
• once i bring the RAID5 disks set and attach it on the QNAP i will switch on the VDP appliance, and let it take a snapshots of the VMs with length of data up to 1 week, at the same time i will send the other RAID5 disks set offsite.

but the issue with this setup that the first 2days of the week will be a long single backup to cover 1 week of incremental data,

Hi All,

I hope all are doing well,
i'm having a difficulty understanding how to do cold storage backup from VMWare environment, currently I'm doing a a local backup to VDP with maximum backup size up to 8TB being saved to QNAP NAS server, the QNAP is hosting the VDP Stores through iSCSI, and it is doing the backup well to the point that i have to make sure there is a replicated version offsite.

to be honest i'm not sure where to start with this, what would be the concept of backing up a live VMWare environment to Cold storage, also as vSphere Data Protection appliance can be hosted only on vmfs volume which is hosted on a NAS or SAN.

kindly advise me how i can cover that gab between the cold storage and the live VDP backup! , and would FreeNAS with ZFS on additional server do a good job in this case? what hardware is required to make a weekly copy of the VDP volume sent offsite,,,

Appreciating your comments.

Kind regards

Might be related to the hardware? i can't say i had the same issue before, but something similar on linux, try to update the motherboard firmware, or try to install another version of the XENSERVER, it would be good to have the ACHI mode active in BIOS again... but thanks for the tutorial anyway.

Small games on mobile like Chess, Hatchi and Brain Dots, mostly puzzle and simple games, i quit playing big games as it was a serious addiction and time waste.

Gongrats!!

Really cool collection !

As far as i know it will stay active until you retire it.
