I have few comments, bq. Backup and Restore Solr collections and it's associated configurations to a shared filesystem - for example HDFS or a Network File System Currently we don't support integration with HDFS directly. This is being done as part of SOLR-9055. bq. location/string/no/The location on the shared drive for the backup command to write to. Alternately it can be set as a cluster property (hyperlink to CLUSTERPROP and document it as a supported property) I don't think we have added support for configuring location via CLUSTERPROP API. We have discussed an alternate approach of configuring file-systems (or Backup repositories) via solr.xml. So I think it would make more sense to configure "default" location as part of that change (instead of enabling it via CLUSTERPROP API).

Any thoughts on this otherwise I'll add it over to the ref guide SolrCloud Backup and Restore of Collections Backup and Restore Solr collections and it's associated configurations to a shared filesystem - for example HDFS or a Network File System Backup command: /admin/collections?action=BACKUP=myBackupName=myCollectionName=/path/to/my/shared/drive The backup command will backup Solr indexes and configurations for a specified collection. The backup command takes one copy from each shard for the indexes. For configurations it backs up the configSet that was associated with the collection and other meta information. key/Type/Required/Default/Description name/string/yes//The backup name collection/string/yes//The name of the collection that needs to be backed up location/string/no/The location on the shared drive for the backup command to write to. Alternately it can be set as a cluster property (hyperlink to CLUSTERPROP and document it as a supported property) async ( copy over from existing docs) Restore command: /admin/collections?action=RESTORE=myBackupName=/path/to/my/sharded/drive=myRestoredCollectionName Restores Solr indexes and associated configurations. The restore operation will create a collection with the specified name from the collection parameter. You cannot restore into the same collection and the collection should not be present at the time of restoring the collection, Solr will create it for you. The collection created will be of the same number of shards and replicas as the original colleciton, preserving routing information etc. Optionally you can overide some parameters documented below. For restoring the associated configSet if a configSet with the same name exists in ZK then Solr will reuse that else it will upload the backed up configSet in ZooKeeper and use that for the restored collection. You can use the Collection ALIAS (hyperlink) feature to make sure client's don't need to change the endpoint to query or index against the restored collection. key/Type/Required/Default/Description name/string/yes//The backup name that needs to be restored collection/string/yes//The collection where the indexes will be restored to. location/string/no/The location on the shared drive for the restore command to read from.

David Smiley commented on SOLR-5750:
I'll give some more time for review, like maybe Monday unless there are further
changes to be done from any review/feedback. Some things I think I want to
change (which I will do today):
* simply remove the Overseer.processMessage case statements for RESTORE &
BACKUP as they simply aren't used. This resolves a nocommit.
* to avoid risk of confusion with "snapshot" possibly being a named commit
(SOLR-9038) in the log statements and backup.properites I'll call it a
backupName, not snapshotName.
Tentative CHANGES.txt is as follows:
{noformat}
* SOLR-5750: Add /admin/collections?action=BACKUP and RESTORE assuming access
to a shared file system.
(Varun Thacker, David Smiley)
{noformat}
About the "shared file system" requirement, it occurred to me this isn't really
tested; it'd be nice it if failed fast if not all shards can see the backup
location's ZK backup export. I'm working on ensuring the backup fails if all
slices don't see the backup directory that should be created at the start of
the backup process. This seems a small matter of ensuring that
SnapShooter.validateCreateSnapshot call mkdir (which will fail if the parent
dir isn't there) and not mkdirs but I'm testing to ensure the replication
handler's use of SnapShooter is fine with this; I think it is.

Although we can do that as part of a separate JIRA, it would be nice if we can get it done as part of this patch itself. I should be able to complete this in next day or two. Also I filed [SOLR-9038|https://issues.apache.org/jira/browse/SOLR-9038] to provide a lightweight alternative to the "full" backup solution implemented by this JIRA. Both these JIRAs need following functionality - Backing up collection metadata - Restore the collection (both index data and collection metadata). Since the APIs defined in this patch use the name "snapshot", I wonder how should we reconcile these two features? I could think of following options, - provide a way to override the behavior (e.g. as an API parameter OR some other global configuration) - rename the APIs here to indicate that its a "full" backup (e.g. CREATEBACKUP/DELETEBACKUP). This will be consistent with the current core level operations (BACKUP/RESTORE).

Defaults to original. * replicationFactor and some other settings are customizable on restoration. * Shard/slice info is restored instead of reconstituted. Thus shard hash ranges (from e.g. shard split) is restored. I still want to: * test asyncId * test property.customKey=customVal passes through * resolve nocommits on how to pass config name & replicationFactor on the SolrJ side Beyond that there are just some nocommits of a cleanup/document nature. I code review would be much appreciated. Should we just use GitHub branches (do I need my own fork?) for that or ReviewBoard? Possibly in this issue but more likely in another, it would be great if collection restoration could honor CREATE_NODE_SET, snitches, and rules.

In the event one is trying to snapshot/restore, I think this can and should be accomplished with collection aliases. So if you intend on using this feature, you would create the collection with a sequence number (or say a/b) and then restore to the next sequence number and when done then switch the alias to a new one, and then delete the old one.

May be we introduce a higher level API (may be at the Directory interface level) ? Any thoughts?

bq. Creates a core-less collection with the config set from the backup ( it
appends a restore.configSetName to it for avoiding collissions )
What if we backup two collections using the same config "foo"? After restore of
the first collection, we will have a config "restore.foo", but what happens
during restore of the second collection? Have not looked at the patch code.
Should it not be a goal that a backup + nuke + restore leaves you with a state
as close to the original as possible, i.e. with one config called "foo", used
by both collections? Perhaps a restore option {{shareConfig=true}} which
creates the config if missing, otherwise reuses what is there?

David Smiley commented on SOLR-5750:
Hello Varun. I've been kicking the tires on this. When I run it explicitly,
it seems to work fine -- no errors. I also tested changing my IP address
between backup & restore, simply by switching my network connection, and I'm
glad to see the restored collection with the correct IPs.
Unfortunately, the test has never succeeded for me. Half the time I get an NPE
from Overseer, the other half the time the test fails its asserts at the end
but before then I connection failure problems that I have yet to look closer
at. The Overseer NPE is curious... clusterState.json is null causing an NPE
when a log message is printed around ~line 214, log.info("processMessage: .
I started to debug that a bit but moved on. I plan to look further into these
things but I wanted to report this progress.
BTW I see no RestoreStatus in the patch.
I was thinking maybe I'll throw up an updated patch in ReviewBoard, but I'm
waiting on INFRA-11152

Does it actually work? The feedback I've seen seem to be around improvements to make it better -- i.e. using a shared filesystem resulting in no actual copying of files. I looked at the patch. On the restore side I noticed a loop of slices and then a loop of replicas starting with this comment: "//Copy data from backed up index to each replica". Shouldn't there be just one replica per shard to restore, and then later the replicationFactor will expand to the desired level? Another question is I wonder if any of these loops should be done in parallel or if they are issuing asynchronous requests so it isn't necessary. It would help to document the pertinent loops with this information, and possibly do some in parallel if they should be done so. > Backup/Restore API for SolrCloud > > > Key: SOLR-5750 > URL: https://issues.apache.org/jira/browse/SOLR-5750 > Project: Solr > Issue Type: Sub-task > Components: SolrCloud >Reporter: Shalin Shekhar Mangar >Assignee: Varun Thacker > Fix For: 5.2, Trunk > > Attachments: SOLR-5750.patch, SOLR-5750.patch, SOLR-5750.patch, > SOLR-5750.patch > > > We should have an easy way to do backups and restores in SolrCloud.

bq. 1) I know we already have "location" via
https://cwiki.apache.org/confluence/display/solr/Making+and+Restoring+Backups+of+SolrCores
but it just seems needlessly risky / error prone. What if a user purposefully
or accidentally overwrites important data? You are giving anyone making a
snapshot call solr's permissions. Beyond that, making "location" a required
param is not the greatest interface. Most of the time when I'm taking a
snapshot I don't even care where it is, I expect the system to just do
something sensible and let me interact with the API with some id (i.e. name).
HDFS and HBase snapshots work in this way, for example. Why not just have a
backup location specified in solr.xml with some sensible default?
bq. 2) On the above point: "I expect the system to just do something sensible
and let me interact with the API with some id (i.e. name)" – why do I pass in a
location for RESTORE? Can't the system just remember that from the backup call?
Nice idea. We could let users specify it within the solr.xml solrcloud tag .
I don't think it should default to anything and if not specified snapshots
should fail. The reason being users not on a shared filesystem need to specify
a shared mount for this to work.
And by specifying it within the solr.xml file , even the restore command
wouldn't need the user to specify the location which will solve your concern in
the 2nd point

snapshot call solr's permissions. Beyond that, making "location" a required
param is not the greatest interface. Most of the time when I'm taking a
snapshot I don't even _care_ where it is, I expect the system to just do
something sensible and let me interact with the API with some id (i.e. name).
HDFS and HBase snapshots work in this way, for example. Why not just have a
backup location specified in solr.xml with some sensible default?
2) On the above point: "I expect the system to just do something sensible and
let me interact with the API with some id (i.e. name)" -- why do I pass in a
location for RESTORE? Can't the system just remember that from the backup call?
3) There's no API for deleting a snapshot?
4) There's no API for listing snapshots? (I don't think this needs to be in an
initial version necessarily)
3) From {quote}So the idea is the location that you give should be a shared
file system so that all the replica backup along with the ZK information stay
in one place. Then during restore the same location can be used.
We can then support storing to other locations such as s3, hdfs etc as separate
Jiras then{quote}
I'm not sure the shard-at-a-time makes sense for shared file systems. For
example, it's much more efficient to take an hdfs snapshot of the entire
collection directory than of each individual shard. I haven't fully thought
through how we support both, e.g. we could do something different based on the
underlying storage of the collection (though that wouldn't let you backup a
local FS collection to a shared FS), or allow a "snapshotType" parameter or
something. I _think_ we can just make whatever you have the default here, so I
don't think we strictly need to do anything in this patch. Just pointing that
out.

When we do a restore, the current impl. restores into a fresh collection. So the backed up data can be on another node not accessible to the restoring collection shard. Hard times on a non-shared file system :). In that case, sure, require it to be set for non-shared file systems (can do it for all filesystems for now, we can change in the future). Or, restore on the same node as the existing shard where you took the snapshot to remove the shared mount requirement? > Backup/Restore API for SolrCloud > > > Key: SOLR-5750 > URL: https://issues.apache.org/jira/browse/SOLR-5750 > Project: Solr > Issue Type: Sub-task > Components: SolrCloud >Reporter: Shalin Shekhar Mangar >Assignee: Varun Thacker > Fix For: 5.2, Trunk > > Attachments: SOLR-5750.patch, SOLR-5750.patch, SOLR-5750.patch, > SOLR-5750.patch > > > We should have an easy way to do backups and restores in SolrCloud.

2 design suggestions
1) Move the operations to {{CollectionsHandler}} . When the process starts add
the backup name and the node that is processing the task to ZK
2) Do not restore all the replicas at once . Just create one replica of a shard
first and then do ADDREPLICA till you have enough replicas

We should have an easy way to do backups and restores in SolrCloud. The
ReplicationHandler supports a backup command which can create snapshots of
the index but that is too little.
The command should be able to backup:
# Snapshots of all indexes or indexes from the leader or the shards
# Config set
# Cluster state
# Cluster properties
# Aliases
# Overseer work queue?
A restore should be able to completely restore the cloud i.e. no manual steps
required other than bringing nodes back up or setting up a new cloud cluster.
