Access Data disappaer

Hi All

We use access as our database, all of the data out of table just disappeared... around (125,000 records).

To make it worse our backup solution had stop working a few weeks back...

Anyidea how the table empty it self? or how to find out what did it?

Cheers

Matt

It may not matter,  but what version of access are you using?  Are you able to undo?  Was the data linked to an excel spreadsheet outside the database? Did you possibly create a copy of the table carrying over only the format?  If you are using a form to input data check to see if the form is still linked to the correct table or query.  These are just a few thoughts.

Basically, only two ways:

1) Corruption
2) Someone deleted the data.

How to find out? Not really ... guess we would have to 'be there'

What happened to the backup?

Access 2010 and no spreadsheets or anything....

We "were" using a online backup services but there server broke or something and they failed to tell us that until i ring them early on today....

I don't think someone deleted it....

I keep trying to import the old stuff we have from a few weeks ago.... and it keeps going on about the database might be corrupt and it wouldn't let me paste any record in... I've click on the  "compact and repair" which seem to of fixed it.  

Is there anyway of pre-eventing any future corruption.... By using SQL Server? or something?

That was my next suggestion ... and you got lucky this time.

"Is there anyway of pre-eventing any future corruption"
Daily Compact & Repair is the *best* preventative maintenance you can do on an Access db ... I guarantee you that.

Of course, SQL Server is an more 'robust' database in that context ... if you have the option.

Well ... yes, HUGE.  
An Access db has a 2GB size limit just to start with ...  so, in 365 days you will be at approx 1 million records ... and depending on the record size, you could well approach the 2GB limit ... or a LOT sooner.

SQL Server is of course more stable and secure than an Access db, but also more expensive.

That at a growing of about + 40 every day.... so in about 119 days will be hitting a million....
