US Patent No. 10409693 - Prepared by Attorney David Tran for Dell EMC and filed by Dergosits & Noah, LLP
Brief Description: FIG. 1B shows an example of stripe alignment, in accordance with some embodiments. The storage device used to store the backed up data 115 may be configured to be stripe aligned. One example of a stripe aligned storage device is the RAID which may combine multiple disks into one logical disk. In the current example, four stripes 175-178 are shown with each stripe being 512 KB in length. There are also eight blocks 180-187, with each block being 256 KB in length. With a stripe aligned storage device, offsets may be used to align write operations to stripe boundaries. This reduces the risk of writing over previously written data. For example, when file 172 (e.g., 750 KB) is written to a storage device, it may be written aligned with the stripe 175 occupying blocks 180, 181 and part of block 182. The remaining portion 170 of block 182 and block 183 may be filled with filler data by the Container Manager (shown in FIG. 2). When file 174 (e.g., 1 MB) is written to the storage device, it may be written aligned with the stripe 177 occupying blocks 184, 185, 186 and 187. The storage device used to store the backed up data 115 may be a non-cloud-based storage device. The non-cloud-based storage device may be referred to as belong to an active tier 116 (shown in FIG. 1A).
