    How important is connection and latency for backup server?

    Hi there,

    I'm about to buy a backup server and have checked the latency from my dedicated server to some hosting companies.

    I've found a great one but the ping is 102ms europe->u.s

    Does this matter?

    The file size is 30GB and I have 7 servers to backup.

    thanks

    latency isn't that big of a deal but connection is. you don't want it to take forever to back everything up.

    i sugest you to keep backup server in same continent. If yu had server in europe, buy backup in europe or viceversa.

    Latency is not a problem, but network speed is important: more speed less backup time

    Latency is not that important, but throughput would be. If the backup takes 12 hours to complete, it'll have a definite impact in your servers performance during potentially peak hours. Make sure throughput is sufficient to complete the backup in time, and then you're good to go.

    I see.

    What throughput would you suggest?

    Thanks

    If you're backing up 30GBs, you'd need really good throughput. Even at 10MB/s (virtually a full 100Mbps), you're looking at nearly an hour of backup time. If you're getting 5MB/s, then almost two hours, etc.

    I assume this is only the first backup? Would you be doing incremental backups from that point on? In that case, then throughput is not that important.

    You also have to consider emergency restore time. If you backup 30GB and you need to restore that after a server crash/rebuild, how long will it take and if that time is acceptable.

    Hmm, I need to think about this a bit more.

    Do you recommend any that has the speeds I need for this?

    Thanks

    How much do you want to back up, and on what time frame?

    100GB over 1 hour will take 222Mbps

    Depending how you back up, thread speed matters too. You may have a 1Gbps connection, but a single transfer might not go faster than 100Mbps. Latency can effect single threaded speeds too.

    Each server has around 80GB to backup. This can easily increase though.
    Time isn't an issue for me. It will be scheduled to backup at 1am.

    I believe a dedicated server would be more suitable?

    What about from a company such as OVH or leaseweb, are their ports enough?

    Thanks
