anne1 Posted January 24, 2011 Posted January 24, 2011 How do people back up Sims? We have been asked to keep weekly or daily copies of all the databases and matching program and doc storage folders for a year. we have various theories of moving the .bak files to a NAS but it all gets very big very quickly, Do other schools have similar issues and how do you sort it? Thanks
GREED Posted January 24, 2011 Posted January 24, 2011 Who has asked you to keep individual daily backups for a year? That seems only so very excessive, given a typical backup is around 3GB+ for some schools, giving you over 1TB of just SIMS backups over a year!
GREED Posted January 24, 2011 Posted January 24, 2011 Most backup solutions (Symantic for example) can tie into the SQL database and backup direct, or like me you can set SQL maintenance plans to backup each day and place a copy of the database in a file location, and backup from there, as well as supporting folders such as doc storage.
TechMonkey Posted January 24, 2011 Posted January 24, 2011 We backup as part of our standard backup process so will have backups daily for the last week, per week for the last month and then 1 quarterly. The standard SIMS backups we only keep a couple because they are blooming huge as they broke the compress feature and SIMS data changes so constantly that any backup too old is nigh on useless.
scholarpack Posted January 24, 2011 Posted January 24, 2011 You can never backup too much. Learnt that the hard way Personally we have now moved to hourly backups of all schools on a weekly rotation.
zag Posted January 24, 2011 Posted January 24, 2011 Dont forget Sims has major upgrades a coupe of times a year making long term backups redundant. We keep it for 3 months here using backupexec direct SQL feature. We also backup the .bak files from upgrades just in case.
36Degrees Posted January 24, 2011 Posted January 24, 2011 SIMS backups are actually managed centrally by the LEA but I still take my own. All backups run nightly through Backup Exec with Monday - Thursday obviously being overwritten weekly and Friday 1 to Friday 4 being overwritten every 4 weeks.
taff Posted January 24, 2011 Posted January 24, 2011 We were told on a recent ISI inspection that we need to have SIMS backups going back 3 years, which was a bit of a heart-stopper! We now archive a monthly SIMS backup onto a DVD and store it in the safe.
GREED Posted January 24, 2011 Posted January 24, 2011 I think a monthy backup going back a year (or 3) is sensible, but daily? so 365 different backup files over a year? What is the use out of interest of having a backup from 165 days ago, compared to 164 or 163... you couldn't restore information from just that backup, without loosing all subsequent information added to SIMS.
maniac Posted January 24, 2011 Posted January 24, 2011 We pay our LEA £500 a year and they backup SIMS for us via our WAN. SIMS is the one system I do my best to have absolutely nothing to do with, and by enlarge I succeed.
matt40k Posted January 24, 2011 Posted January 24, 2011 Might be worth compressing those .bak - maybe Tidy Backups can help
anne1 Posted January 24, 2011 Author Posted January 24, 2011 Thanks for all the comments, it was seen that we might have to get data back for say a single child up to a year ago if something had got lost somehow. I think the plan was to restore to a secondary system , get the data off and reenter it. And yes the files are huge, ours get to 5 gb a day. Keeping the weeklies for a year has now been seen as acceptable given the amount of date. But you do have to have sims program files and doc storage in sync for this method to be useable. It's not disaster recovery , but individual data files. Do many people do this? I gather ISI is independant school inspection, anyone know if ofsted have any similar timescale?

I think some people miss-understand that SIMS stores all it's old data in-definitely in its live database and you can go back and view it at any point, just search for a student record and change the filter to 'ever on roll' and you'll see all your old student records still there. When you see standards like 'must keep records for 7 years' that doesn't mean you have to keep the backup tape from 7 years ago for that length of time, as all the information is still accessible in the live system (you just need to ensure it is backed up in the normal way) When I used to have responsibility for backing up SIMS, I used a normal tape rotation consisting of mon-thurs tapes that were re-used weekly, 4 friday tapes used in rotation and 12 end of month tapes and even that is quite over the top in my opinion as the data on any tape more than a few weeks old would be so out of date it would be useless.

anne1 Posted January 27, 2011 Author Posted January 27, 2011 Tidybackups looks useful, thanks for the advice, however we are asked to keep the .bak files , is it possible to use it to move the files rather than delete? The data manager wants to be able to get data back from up to a year ago by restoring the database to a duplicate sims system on a partition on his PC. And if it could make tea as well that would be really helpful!
rh91uk Posted January 27, 2011 Posted January 27, 2011 We hold backups for a quarter here, very useful when you want to restore to a local test server and go "when was that change made?"

The data manager wants to be able to get data back from up to a year ago by restoring the database to a duplicate sims system on a partition on his PC. And if it could make tea as well that would be really helpful! As has been said before, all data is stored in the database, so you don't need a year old backup file to see data from last year, however, what it will show you is if a specific piece of data changes, so if some info was changed a year ago, you'd need the year old backup, and any one from after the change to see the difference. However, is that very likely? Some areas, such as changing names, addresses, school groups / classes, are stored in the history within sims, so it's still possible to see that. Things where it might apply are grades stored with a result set (no history), behaviour records (easily deleted) etc. I keep as much data as i can, however, really a typical, grandfather, father, son strategy, should be more than sufficient. After many updates, a lot of backup files wont restore anyway, unless you keep virtual copies of the system prior to each upgrade, which is something i'm considering, via a snapshot.
matt40k Posted January 28, 2011 Posted January 28, 2011 Mmm... I could get it to allow you to move them, I assume to a network location? Making Tea is easy, it's transporting that's the problem!!

Actually, that's not a bad idea, if you can somehow get it into a typical backup strategy, so it goes into Folders labelled by the week, then moved to a monthly one, so it's actually doing the rotation for you. With the option of deleting when it rotates or just to maintain the archive. Then it's up to the netman or whoever to just delete a folder rather than look through a list of files, which is what i do at the mo'.
