Why Create Backup Files?
Why should you create backup files? The obvious answer to this question is protect against some type of disaster in which your database file might get destroyed. Of course, there are any number of ways your database file can be “destroyed”: 1) your computer’s hard drive becomes irreversibly corrupted (e.g., defective, virus, etc.), 2) your computer is destroyed by a disaster (tornado, fire, etc.), or 3) your computer is stolen.
It doesn’t matter how you lose your database file, you need a backup to avoid having to start from the beginning. Just think about what would happen if you lost your database file and had no backup. This is a no-brainer. You must have a backup!
GS Offers a Convenient Backup Feature
GS has a new feature that allows you to conveniently back up your database file. Take advantage of it!
GS Creates Two Types of Backup Files
• GS will create two types of backup files for you:
1) an exact copy, or snap shot, of your database file as it was when you created the backup copy, and
2) a Zip file containing a compressed copy of your database file.
• What is the difference between the two types of backups?
Most notably, there is a huge difference in the size of the two types of backups. The exact copy (snap shot) is the exact same size as the file it was copied from. The Zip file is a compressed version of the database file, meaning it is likely about 10 percent or less the size of the exact copy.
There is another significant difference. You can replace your current “production” database file (i.e., the one currently being used by GS) with the exact copy (snap shot) and GS would work fine. If you try to replace the “production” database with the Zip backup database file, GS will not recognize the file. To use the Zip database file you would have to “unzip” it first.
You should never attempt to replace your production database file with a backup without assistance from Technical Support. It is probable that you will lose data.
How to Create Backup Database Files Using GS
At the end of every day, you should create backups of your database file. To create backup files using GS follow these steps:
• Step 1: Exit GS and Click on Yes to create a backup file.
• Step 2: Select the database in the listing you wish to back up.
• Step 3: Click on Back Up Selected Database.
This will create an exact copy (snap shot) of the “production” database that you are currently using.
Note 1: The backup database file created using this procedure will be given the same name as the “production” database, but will also have a date stamp on it. For example, for the City of Lincoln, the backup copy of the database will have the name Lincoln_07312009.accdb where the date stamp is the date you created the backup.
Note 2: The backup database file will be located in the following folder on your hard drive: “C:\Program Files\GS\GSDatabases\.accdb”.
• Step 4: Click on Zip Selected Database.
This will create a Zip file containing a compressed version of your “production” database file.
Note 1: The Zip backup file created using this procedure will be given the same name as the “production” database, but will also have a date stamp on it, and it will have the file extension “zip”. For example, for the City of Lincoln, the backup copy of the database will have the name Lincoln_07312009.zip where the date stamp is the date you created the backup.
Note 2: The Zip backup file will be located in the following folder on your hard drive: “C:\Program Files\GS\GSDatabases\.zip”.
• Step 5: Click on Upload Zipped Database (optional).
This will upload the Zip file to the CMW website where we can download the file and examine it.
This Step is necessary only if you want us to test your backup, or we need to examine it for possible corruption.
• Step 6: If you uploaded a Zip file to the CMW website, you should send us an email to alert us that the file has been uploaded. Also, you should describe briefly why you uploaded the file. That is, what are you expecting us to do with the file?
• Step 7: Wait for an Email response from us.
• Step 8: Start Windows Explorer (My Computer) to locate the backup files you just created. Both files should be located in the folder C:\Program Files\GS\GSDatabases.
Keep in mind the name of the files you are trying to locate:
.accdb (e.g., Lincoln_07312009.accdb)
.zip (e.g., Lincoln_07312009.zip)
Be careful not to get confused when you are trying to locate the files as you likely will have other similar-looking file names in the same folder. Also, you will see you current “production” database () and the other (less important) GS database file, GSEntities.accdb.
This step is only intended to help you understand where the backup files are located.
Important: Keep in mind that these backup files are still on your hard drive. If you lose your computer, you lose your backups. Therefore, periodically you should copy the most recent Zip backup file to an external source for safekeeping (see next step).
• Step 9: At the end of each week, we suggest that you copy your zipped backup file from your computer to an external hard drive (or some other external storage media). You can use Windows Explorer (My Computer) to do this.
REMEMBER: If you lose your computer, you lose your production database and all of the backups on the computer. That is why it is important that you periodically copy a backup file to an external source.
PLEASE contact technical support if you need assistance with this.
• Step 10: Every month or so, it doesn’t matter how often, you can delete the backup files on your computer. You can use Windows Explorer (My Computer) to do this.
BE CAREFUL: When you delete backup files, make sure you delete only those files that have Date Stamps on them.
PLEASE contact technical support if you need assistance with this.
• If anything appears to go wrong with any of these backup procedures, contact Technical Support IMMEDIATELY. You likely will make things worse by trying to fix the problem without our assistance!
How to Repair a Possible Corrupted Database File
Any database file can possibly get corrupted. When a database file gets corrupted, generally you have two options: 1) repair the corrupted database file, or 2) remove the corrupted database file and replace it with the most recent backup.
• How do you know if your GS production database file is corrupted?
If your production database is corrupted, you will know it when you start up GS. You will get an “unexpected error.”
If this happens, your best course of action is to contact Technical Support immediately.
• How does the GS production database file get corrupted?
By far, the most common cause of Access database corruption is some type of disconnection while processing is taking place. For example, if you are processing a report using GS and the computer loses power, the database can get corrupted.
• What to do if you think your production database file is corrupted?
Without question, if you think your production database file is corrupted you should contact Technical Support immediately. We will discuss with you the best approach to take.
• Is it preferable to repair the corrupted database, or replace it with a backup?
The decision on whether to repair the corrupted database or replace it with a recent backup depends on primarily on how much work you have done in GS since your last backup. For example, if the database file is corrupted early in the morning while you are processing a lengthy report, and you have not entered any new transactions or changed any information in GS since backing up the night before, then you can simply replace the corrupted file with the previous night’s backup.
On the other hand, if the database is corrupted late in the day, after you have entered all of the meter readings for the utility bills, your first option should be to try to repair the corrupted database. Otherwise, you would have to re-do all of the work you did that day.
• How do you repair the corrupted database?
Probably you should first try to use GS to repair your corrupted database file. To use GS, follow these steps:
Step 1: Start GS.
Step 2: Exit GS and Click on Yes to create a backup file.
Step 3: Select the database in the listing you wish to repair.
Step 4: Click on Compact and Repair.
Step 5: Click on Close.
Step 6: Start GS again to see if the database was repaired.
If this procedure does not repair the corrupted database you should follow the above steps to back up the corrupted database and upload it to the CMW website. Be sure to send an email to Technical Support explaining you have uploaded a suspected corrupt database file.
We will attempt to repair the file and, if successful, place the repaired database back on the CMW website for you to download. We will notify you by email and also help you to replace the corrupted file with the repaired database file.
• How do you replace the corrupted database with a backup database file?
To replace the corrupted database with a backup database file do the following: 1) disable the current production database (the corrupted database) by re-naming it, 2) create a copy of the most recent backup copy of the database (copy and paste), and 3) re-name the copy of the backup to the original name of the production database.
• REMEMBER: If you suspect you have a corrupted database file, contact Technical Support immediately.
Return Files – Created by Technical Support
It is possible, although rare, that Technical Support will ask you to upload your database for the purpose of making some changes to the data that you are, for whatever reason, unable to perform yourself.
In such cases, you must upload you database in the normal manner. Technical Support will then download your database, make the appropriate changes, and upload the updated database back to the website.
You will then be instructed by Technical Support how to re-install the updated database to your computer so you can resume your regular work.
Critically Important! After you upload your database you SHOULD NOT attempt to make any updates to your “production” database. You can view records and create reports, but you absolutely should not make any changes to any data. If you do, those changes will not be there when you re-install the changed database returned to you by Technical Support.
Instructions Related to Database Return Files
• Tech Support downloads user database and puts it into production on the tech support computer to make changes.
• Tech Support makes necessary changes to user database and creates a zipped backup.
• Tech Support renames the zipped backup using the name of the database on the user’s computer:
Assume database name on user’s computer is “lincoln”. The zipped database will be renamed: lincoln_Return.zip. If the database name is “Lincoln”, the zipped database will be renamed: Lincoln_Return.zip.
Important: The spelling of the return file must match the name on the user’s machine and the name is case sensitive for purposes of downloading the return file. To determine the spelling of the database name on the user’s computer the user can go to GS Startup/Initial Entity Setup, select the entity, edit, and the database name will be on the screen.
• User downloads the changed file using the Backup feature (Download button). The zipped return database file will automatically be copied to the user’s GS database location.
• Tech support must then walk the user through the steps to unzip the return database file and use it to replace the production database.
In this step the production database being replaced (e.g., Lincoln.accdb) should not be deleted. Instead it should be renamed and saved if something goes wrong, and it must be re-installed.
