摘要： A basic property of flash memory is that: a 0-bit can be changed into a 1-bit, but not vice-versa, which severely limits the possibilities of reusing storage space with new data. A family of new coding methods is presented that enables double use of the memory, effectively expanding the combined amount of stored data. This can then be used as a compression booster, adding an additional layer to, and improving the compression of some rewriting methods that are not context sensitive.

摘要： Methods, computer systems, and computer program products for calculating a remainder by division of a sequence of bytes interpreted as a first number by a second number is provided. A pseudo-remainder by division associated with a first subsequence of the sequence of bytes is calculated. A property of this pseudo-remainder is that the first subsequence of the sequence of bytes, interpreted as a third number, and the pseudo-remainder by division have the same remainder by division when divided by the second number. A second subsequence of the sequence of bytes interpreted as the first number is appended to the pseudo-remainder, interpreted as a sequence of bytes, so as to create a sequence of bytes interpreted as a fourth number. The first number and the fourth number have the same remainder by division when divided by the second number.

摘要： For scalable data deduplication working with small data chunks in a computing environment, for each of the small data chunks, a signature is generated based on a combination of a representation of characters that appear in the small data chunks with a representation of frequencies of the small data chunks. The signature is used to help in selecting the data to be deduplicated.

摘要： Systems and methods enabling search of a repository for the location of data that is similar to input data, using a defined measure of similarity, in a time that is independent of the size of the repository and linear in a size of the input data, and a space that is proportional to a small fraction of the size of the repository. The similar data segments thus located are further analyzed to determine their common (identical) data sections, regardless of the order and position of the common data sections in the repository and input, and in a time that is linear in the segment size and in constant space.

摘要： Exemplary method, system, and computer program product embodiments for an incremental modification of an error detection code operation are provided. In one embodiment, by way of example only, for a data block requiring a first error detection code (EDC) value to be calculated and verified and is undergoing modification for at least one randomly positioned sub-blocks that becomes available and modified in independent time intervals, a second EDC value is calculated for each of the randomly positioned sub-blocks. An incremental effect of the second EDC value is applied for calculating the first EDC value and for recalculating the first EDC value upon replacing at least one of the randomly positioned sub-blocks. The resource consumption is proportional to the size of at least one of the randomly positioned sub-blocks that are added and modified. Additional system and computer program product embodiments are disclosed and provide related advantages.
