  • Backup solution for 800GB.

    Hi,

    We're looking for a backup solution to backup around 800GB. These are mainly CAD files with PDF, Word, Excel files.

    Ultrium4 Tape Drive might be interesting but it's quite expensive. I was wondering if anyone had any idea for a backup solution for this.

    Also, the quantity of DATA should grow to around 3TB since a merge is expected.

    I'm looking forward for your ideas !

    Best regards,

    USB HDD maybe
    They are cheap and fast but a little less safe to carry around.

    Is that 800GB compressed size?
    cheers

      Re: Backup solution for 800GB.

      Is this for an onsite (online or offline) or offsite backup?

      In case my use of those terms is different from others...

      Onsite online refers to onsite backups to media which is kept powered up, such as NAS.

      Onsite offline refers to onsite backups to 'offline' media - tapes, USB hard drives etc, which are removed after the backup and preferably in a fire safe.

      Offsite backups... shouldn't need explaining

          True, but online offsite and online onsite are pretty similar... but yes I suppose the differences are sufficient to justify mentioning.

            online offsite can mean one of 2 things:
            a co-lo situation
            online backup solution like www.mozy.com

            offline offsite = tapes / media stored at an Iron Mountain facility.

            ANYWAY, back to the topic, do you have any constraints on this idea? time / money / location, ease of use, etc? Currently we're researching a backup server w/ appx. 6 TB of USEABLE storate over an 8 drive RAID 5 or 6 w/ a hot swap.

            Kinda scary considering I was messing around w/ the idea of a basic RAID 5 array w/ 3 or 4 TB for home...

              You mean you don't keep the tapes in your sock drawer?

                Hi,

                Thanks for the replies.

                The 800GB is uncompressed.

                We need an onsite offline solution such as tape, etc. We're currently trying to backup the 800GB to USB HDD but it takes over 3 days to do a full backup.

                Best regards,

                  Try splitting it up into chunks and backing up each chunk to something like a gigabit NAS. Unless you fancy splashing out on a tape library... my way's cheaper

                    You will have to backup changes only, ideally at the sector level. Currently for one of my clients I backup 250gb in about 2 minutes, only the changes (every hour).

                    Then you can merge the changes into one image file and copy to wherever.

                    Would that work?

                      Full backup on a Friday (not ideal if it's still running for a bit on Monday morning, but any half decent backup software will be using shadow copies to avoid causing disruption) and incremental backups Monday-Thursday maybe?

                        Backup is starting at 6PM on friday, still have 20+ hours left on Monday morning :\

                        I'm in the process of copying everything to a NAS. Though, the NAS is not fire proof hehe. I would need a solution to take the backup out of the building. LTO4 along with a backup library might be the solution. Would it be possible to use 2-3 tapes everyday to do a full backup or just use 2-3 tapes to do a full backup once a week then incremental.

                          From an earlier post I was under the impression this was intended to be an onsite offline backup... in any case, when backing up to tape I always favour full backups. Can't really give any idea of how long it would take without trying it... you could probably make an educated estimate based on the amount of data, the performance of the drive and the bandwidth available on the system bus.

                            The SAN where the DATA is stored uses 300GB 15K RPM SAS drives in a 0+1 RAID. Everything is connected through fibers to the host server. I guess there aren't too much bottlenecks here. A tape drive connected through fibers to the HBA on the host would be the best solution i think.

                              One option would to look at getting a Firewire 800 drive and card, this will give you double the bandwidth over your USB drive and should reduce the backup time by a fair bit
