1 validation
The process of comparing files on local volumes with their associated data in secondary storage by Remote Storage. Volumes that are validated ensure that the correct data is recalled from remote storage when a user attempts to open the file from a local volume. -
2 checksum
"A calculated value that is used to test data for the presence of errors that can occur when data is transmitted or when it is written to disk. The checksum is calculated for a given chunk of data by sequentially combining all the bytes of data with a series of arithmetic or logical operations. After the data is transmitted or stored, a new checksum is calculated in the same way using the (possibly faulty) transmitted or stored data. If the two checksums do not match, an error has occurred, and the data should be transmitted or stored again. Checksums cannot detect all errors, and they cannot be used to correct erroneous data." -
3 thread safety
The ability for multiple threads to access and share data in a correct way. -
4 validation
"The process of confirming that data passing into the system is correct and complies with predefined rules, definitions, or parameters."
