On step 4 of the wizard, specify the compression, encryption, and optimization options for your backups.
To compress the backup, select the Compress backup check box and select the compression level by moving the slider. For more information about compression levels, see Compression levels.
For full database backups, you can click Compression Analyzer to perform a test on the databases to check which compression level will produce the best result for your requirements. For more information about the Compression Analyzer, see Compression analyzer.
To encrypt the backup, select the Encrypt backup check box, then type a password for the backup in Password, and again in Confirm password.
Choose 128-bit or 256-bit encryption. You must remember your password; if you do not, you will not be able to access the encrypted backup.
If you are backing up to a Single file or Single backup file, mirrored to second location, SQL Backup Pro can use multiple threads to create the backups. This can speed up the backup process. Select the Use multiple threads check box, and type or select the number of threads up to a maximum of 32. For more information about using multiple threads, see Optimizing backup speed.
Maximum transfer size specifies the maximum size of each block of memory to be used when SQL Backup Pro stores backup data. The default value is 1024 KB; you may want to change this value if a SQL Server reports that it has insufficient memory to service requests from SQL Backup Pro.
Maximum data block specifies the maximum size of data blocks to be used when SQL Backup Pro stores backup data. The default value is 4096 KB.
Note that if you want to specify the network transfer packet size, change the connection properties for the SQL Server. For more information, see Connection Properties.
The Network resilience settings control retry behavior following a read/write error whenever SQL Backup Pro:
- writes a backup file to disk
- copies a backup file to another disk location
Read/write errors are most likely to occur when SQL Backup Pro is processing files through a network connection.
In most circumstances, you can leave On failure, retry after and Retry up to (n) times at their default values (30 seconds, and 10 times). To disable retries completely, specify Retry up to 0 times.
