    What backup methods do you use?

    We are considering our backup process and it would be interesting to see how some others do things.

    At the moment our data is copied (using RoboCopy) across the network to a backup PC (Windows XP machine with a big drive). Once there it is compressed (using 7-Zip) to save space.

    With this method we can keep about 2 weeks worth of backups, but we would like more. We do a normal backup on a Friday (starting at 6pm) and incremental backups each week night (Mon - Thur) at 6pm.

    Typical user data for a normal backup is just over 100 GB. A normal backup with this much data takes 3 days - not good! Obviously compressing the data on the server before copying it across the network would improve things, but we would like to consider other methods too.

    Non user data is copied to a second backup machine in a similar way.

    Any thoughts please on the best way forward for this. We will be happy to go with a commercial product. Ease of user data restores is also an issue. At the moment we have to reset permission on user folders when data is restored to them - no big deal, but a nusiance non the less.

    Thanks for reading and replying.

    Re: What backup methods do you use?

    We've got Veritas 10 with Remote Agents to backup from other servers, Advanced Open File Option to... backup open files and Intelligent Disaster Recovery which rocks.

    We backup about 180GB in 4 hours to an SDLT320 drive with a tape for each day and we rotate the tapes each week.

    No problems at all, doesn't take too long to restore data and the one time I had to use the IDR stuff, it worked :P

    I also use Veritas onto an HP Ultrium tape drive.

    Full backup every Friday night, incremental Monday-Thursday. Switch to incremental for holidays.

    Swap tape on Friday, then on Monday morning as the full backup > 200 Gb.

    All scheduled - easy-peasy.

    Also use Veritas OFO & IDR, haven't needed to test IDR yet, fingers crossed!!!

    Re: What backup methods do you use?

    Admin Server:

    Backup onto removable hard disks, daily, stored in fireproof safe.

    Curriculum Servers:

    Volume Shadow Copy everynight.
    Followed by a Robocopy onto another PC other end of the school.
    Once a week backup on to tape in a fireproof safe.

    This way, kids can get there own backups back.
    If the server fails, there is an indentical working copy that i can redirect the clients too, so VERY small down time.

    If we have a fire, we lose no more than 4 days of kids work since we have weekly backups in the safe (If the school had a fire that bad it took the servers i do not think people would worry about losing 4 days work.

    Now where was it I read that fireproof data safes werent worth the money, most only handle 1-2 hours before they give up and melt.

    Yes a fireproof safe will have a rating of how many hours it can survive this is how long it will protect the data for not melt itself though.

    I suppose what you need as part of your DR plan is that the fire brigade are notified where the safe is so that they could rescue it?

    Mines in my first floor office but I may change that now I've thought about it.

    Re: What backup methods do you use?

    I use Retrospect Multi Server version (unlimited network use) with Exchange and SQL clients and backup to a Tanberg LTO2 Autoloader (only £2500). Works OK and is quite fast.

    I keep my tapes in a separate block to the servers which should help protect against the risk of fire - tape safes are expensive.

    Tape safes are expensive but then how valuable is the data held within?

    hence why it is stolred in a different building... and chances are that the fire brigade aren't going to go fishing for your tape safe wilst the building is burning down.

    Re: What backup methods do you use?

    We use Legato Networker with a Certance Ultrium LTO 2 tape drive. My manager takes the backup tapes home with him every night so data is stored off site.

    We've also enabled volume shadowing on our new Win2k3 file server and that in itself has completely eliminated the need for silly little restores.

    Works very nicely

    Re: What backup methods do you use?

    I'm about to roll out an LEA wide solution for remote backups, all schools will be backed up to a central location in the data centre then mirrored to a second location. The data is sent/store in an encrypted state and schools are the only ones with the encryption key.

    Cost to schools, about £300 per annum.

    Surely there must be something wrong with that robocopy script?!?

    I do a full backup every night of about 100Gb - and that to a terrastation with a mobile phone CPU [apparently! :P]

    Mon to thurs then 4 fridays giving me 4 weeks

    Re: What backup methods do you use?

    My standard method is based on a command script which does the following;

    1 - Call the EXE which makes a SIMS backup (admin servers only)

    2 - Create a new tape name (based on date/time)

    3 - Execute NTBackup with a predefined .BKS selection file

    The whole thing runs as a Windows scheduled task (not via NTBackup) under the security context of a dedicated backup user account that has Administrator level access.

    The system works fine as long as the data fits on a single tape.

    I don't think this solution would be useful for anything but the simplest of sites but I thought I'd throw it it to show how penny pinching I am!
