This patch series implements the functionality to extend the current
sync jobs in pull direction by an additional push direction, allowing
to push contents of a local source datastore to a remote target.
The series implements this by using the REST API of the remote target
for fetching, creating and/or deleting namespaces, groups and backups,
and reuses the clients backup writer functionality to create snapshots
by writing a manifeset on the remote target and sync the fixed index,
dynamic index or blobs contained in the source manifest to the remote,
preserving also encryption information.
Thanks to Fabian for further feedback to the previous version of the
patches, especially regarding users and ACLs.
Changes since version 4 of the patch series:
- Rebased onto current master
Most notable changes since version 3 of the patch series include:
- Rework access control permission checks to resemble the pull based
logic more closely.
In order to perform a full sync in push direction, including
permissions for pruning contents with remove vansished, a acl.cfg
looks like below:
```
acl:1:/datastore/source-store:syncoperator at pbs:DatastoreReader
acl:1:/remote:syncoperator at pbs:RemoteAudit
acl:1:/remote/remote-target/target-store:syncoperator at pbs:RemoteDatastorePrune,RemoteSyncPushOperator
```
- Modify access to sync jobs now requires `DatastoreAudit` for both,
pull and push sync jobs
- Fix previously incorrect privs required for removing target
namespaces
- Fix performance bottleneck by not reading known chunks from source,
by sending `MergedChunkInfo` instead of `ChunkInfo` over to the
upload stream
- Factor upload statistic counters and structs out into their own
module and provide methods for easy conversion
- Implement `map_to_target` helper for easier/more readable source to
target mapping for namespaces
- Optimize namespace creation on target, only try creating non
pre-existing namespace components.
- Avoid temp file for manifest and upload source manifest directly
- Not failing on deletion for protected snapshots is now opt-in
- Refactor api endpoint `version` in order to be able to fetch api
version for target
- Reworked `SyncDirection` api type, use `api` macro to reduce code
Most notable changes since version 2 of the patch series include:
- Add checks and extend roles and privs to allow for restricting a local
users access to remote datastore operations. In order to perform a
full sync in push direction, including permissions for namespace
creation and deleting contents with remove vansished, a acl.cfg looks
like below:
```
acl:1:/datastore/datastore:syncoperator at pbs:DatastoreAudit
acl:1:/remote:syncoperator at pbs:RemoteSyncOperator
acl:1:/remote/local/pushme:syncoperator at pbs:RemoteDatastoreModify,RemoteDatastorePrune,RemoteSyncPushOperator
```
Based on further feedback, privs might get further grouped or an
additional role containing most of these can be created.
- Drop patch introducing `no-timestamp-check` flag for backup client, as pointed
out by Fabian this is not needed, as only backups newer than the currently
last available will be pushed.
- Fix read snapshots from source by using the correct namespace.
- Rename PullParameters `owner` to more fitting `local_user`.
- Fix typos in remote sync push operator comment.
- Fix comments not matching the functionality for the cli implementations.
