Cloud-Based Data Storage and Recovery System with Tiered Storage Management
Data resiliency in a cloud-based storage system, including: receiving, for storage within a first tier of cloud storage of the cloud-based storage system, one or more segments of data; generating, for each of one or more shards of data of the one or more segments of data, self-describing information for recoverability of the one or more shards of data; and storing, within a second tier of cloud storage of the cloud-based storage system, both the one or more shards of data and the generated self-describing information for recoverability of the one or more shards of data.
1 . A method comprising:
for data that is received for storage within a first tier of cloud storage of a cloud-based storage system, generating recovery information that is sufficient to enable recovery of the data; and
enabling recovery of a portion of the data based at least in part on recovery of another portion of the data using the recovery information.
2 . The method of claim 1 , further comprising removing the recovery information from a second tier of cloud storage of the cloud-based storage system.
3 . The method of claim 1 , further comprising distributing the recovery information on a number of storage elements of the cloud-based storage system.
4 . The method of claim 1 , wherein the recovery information includes information about distribution of the data in the cloud-based storage system and redundancy information.
5 . The method of claim 1 further comprising generating recovery information that is sufficient for recovery of the data.
6 . The method of claim 1 , wherein the first tier of cloud storage includes a plurality of cloud computing instances.
7 . The method of claim 1 , wherein the first tier of cloud storage is block-level storage.
8 . The method of claim 1 , wherein a second tier of cloud storage includes an object storage.
9 . The method of claim 8 further comprising storing the data in the second tier of cloud storage of the cloud-based storage.
10 . The method of claim 9 , wherein the first tier of cloud storage includes a level of storage granularity that is block-level, and wherein storing the data includes transferring the data from block-level storage in the first tier of cloud storage to object storage in the second tier of cloud storage.
11 . The method of claim 1 , wherein the first tier of cloud storage of the cloud-based storage system stores a subset of a volume of data.
12 . The method of claim 1 , wherein the data are part of a dataset, and wherein the cloud-based storage system synchronously replicates the dataset with one or more other storage systems.
13 . A cloud-based storage system within a cloud computing environment, the cloud-based storage system including:
one or more cloud computing instances providing a first tier of cloud storage;
a second tier of cloud storage; and
one or more storage controller applications, each storage controller application executing in a cloud computing instance, wherein the one or more storage controllers are configured to:
for data that is received for storage within a first tier of cloud storage of a cloud-based storage system, generate recovery information that is sufficient to enable recovery of the data; and
enable recovery of a portion of the data based at least in part on recovery of another portion of the data using the recovery information.
14 . The cloud-based storage system of claim 13 , wherein the one or more storage controllers are further configured to remove the recovery information from the second tier of cloud storage of the cloud-based storage system.
15 . The cloud-based storage system of claim 14 , wherein the recovery information is removed from the second tier of cloud storage of the cloud-based storage system after the data has been written to the second tier of cloud storage of the cloud-based storage system.
16 . The cloud-based storage system of claim 13 , wherein the one or more storage controllers are further configured to generate recovery information that is sufficient for recovery of the data.
17 . A non-transitory computer readable storage medium storing instructions which, when executed, cause a processing device to:
for data that is received for storage within a first tier of cloud storage of a cloud-based storage system, generate recovery information that is sufficient to enable recovery of the data; and
enable recovery of a portion of the data based at least in part on recovery of another portion of the data using the recovery information.
18 . The non-transitory computer readable storage medium of claim 17 , wherein one or more storage controllers are further configured to remove the recovery information from a second tier of cloud storage of the cloud-based storage system.
19 . The non-transitory computer readable storage medium of claim 18 , wherein the recovery information is removed from the second tier of cloud storage of the cloud-based storage system after the data has been written to the second tier of cloud storage of the cloud-based storage system.
20 . The non-transitory computer readable storage medium of claim 17 , wherein one or more storage controllers are further configured to generate recovery information that is sufficient for recovery of the data.
