Jon Lloyd Duerdoth | why not just encrypt the tables?
A backup that is encrypted vs a backup of encrypted tables is (essentially) "non-compressible" anyway. Jon Tim Young [Elevate Software] wrote: > Robert, > > << Can I encrypt the backup file without modifying the engine? >> > > Unfortunately, no. > |

Those have to be encrypted. There is no need for encryption in the regular day to day operations.

If so, then there's a way to access the encryption/decryption routines in the engine to use them. -- Tim Young Elevate Software www.elevatesoft.com |

Jon Lloyd Duerdoth | I actually have the opposite situation where the tables are
encrypted but the content of the backup is unencrypted tables. Unless the size of the tables is too large, consider a 2-step backup where you make a copy of all tables (encrypting them) and then do the backup from the encrypted tables. My backup is only several megs so this approach may not be feasible for you.

I think I'll just put the backup file thru a ZIP compress (which will not really compress anything) with encryption, that should do the trick. Robert |

Jon Lloyd Duerdoth | Simple but effective! There are versions that have
"superior" encryption levels (but you would need perhaps a non-standard zip program) Jon Robert wrote: > "Jon Lloyd Duerdoth" <jld@welshdragoncomputing.ca> wrote in message > news:E4330170-82A2-40B1-B197-6CFC8FD534BB@news.elevatesoft.com... >> Unless the size of the tables is too large, consider a 2-step >> backup where you make a copy of all tables (encrypting them) and >> then do the backup from the encrypted tables.
