.... and roll forward concepts to ensure consistency during transactions with commit and abort [14] Several systems have used copy on write and differencing techniques that are common to versioning systems to decrease the bandwidth required during system backup or distributed version updates [4, 6, 26, 31, 32]. Some of these data differencing techniques [5, 26, 31] could be applied to CVFS to reduce the space utilization of versioned data. 8 Conclusion This paper shows that journal based metadata and multiversion b trees address the space inefficiency of conventional versioning. Integrating them into ....

....the secondary copy as soon as they are received in the secondary host (a special case of the volatile immediate report of section 2. 5) Network Appliance SnapMirror: this product uses asynchronous, write coalescing batched file system updates that are applied atomically at a remote file server [Patterson2002] The WAFL file system is used to keep track of the blocks that have been updated, including which blocks are still in use and worth propagating. The WAFL file system always operates in a no overwrite mode, so it readily supports applying a coordinated set of updates atomically. 3 The Seneca ....
....from the active server to the semi active (once failed) server, and maintained a water mark to indicate which blocks had been copied and which had not. Mime [Chao1992] a shadow writing storage system, avoided synchronous metadata updates using a log and barriers. The SnapMirror paper [Patterson2002] contains some similar observations to ours, but its focus was on execution performance, rather than the details of the protocol or its correctness; long batch lengths tens of minutes to hours, rather than seconds; and the support needed in the WAFL nooverwrite file system for block coalescing, ....

....and limited bandwidth, which alleviates the necessity of dedicated communication links to all replicas. 1 Introduction It is well understood that important data need to be protected from catastrophic site failures. High end and midrange storage systems, such as EMC SRDF [4] and NetApp SnapMirror [17], copy data to remote sites both to reduce the amount of data lost in a failure, and to decrease the time required to recover from a catastrophic site failure. Given the plummeting prices of disk drives and of high speed networking infrastructure, we see the possibility of extending the ....
....2 way replication, and uses an all or none assignment of the blocks of a logical volume to SEs, rather than a declustering scheme. StarFish uses a single HE (on a quasi static basis) to manage any particular logical volume, and thereby avoids distributed consensus. Network Appliance SnapMirror [17] generates periodic snapshots of the data on the primary filer, and copies them asynchronously to a backup filer. This process maintains a slightly out of date snapshot on the backup filer. By contrast, StarFish copies all updates on the fly to all replicas. The iSCSI draft protocol [19] is an ....

....requires some level of support from the applications. Also, these two systems do not address deep archival capability and availability. venti [4] provides versioning capability through a block level interface. It uses block level hashing to avoid storing redundant copies of block data. SnapMirror [5] provides versioning by taking advantage of meta data stored in the underlying file system. The Elephant file system [6] provides versioning capability and retention policies that can be applied at a file level. However, none of the above techniques provide semantic storage and retrieval ....
