glacier-client

Build Status Maven Central

Amazon Glacier backup tool with the following features

  • vault management: create, describe, list, delete
  • archive management: upload, delete, download
  • local catalog management: add, list, delete, synchronize with Glacier inventory

glacier-client can be used through its API in Scala programs or as an interactive backup CLI (via REPL).

basic operations

Start up Scala REPL

Welcome to Scala 2.11.11 (Java HotSpot(TM) 64-Bit Server VM, Java 1.8.0_151).
Type in expressions for evaluation. Or try :help.

List the names of available AWS regions

scala> fi.markoa.glacier.GlacierClient.regions
res0: Array[String] = Array(us-gov-west-1, us-east-1, us-east-2, us-west-1, us-west-2, eu-west-1, eu-west-2, eu-central-1, ap-south-1, ap-southeast-1, ap-southeast-2, ap-northeast-1, ap-northeast-2, sa-east-1, cn-north-1, ca-central-1)

Create a Glacier client that connects to the us-west-2 region

scala> val c = fi.markoa.glacier.GlacierClient("us-west-2")
c: fi.markoa.glacier.GlacierClient = fi.markoa.glacier.GlacierClient@11b6e34a

Create new vault. The ID (or ARN) for the newly created vault is returned.

scala> c.createVault("test-vault-1")
res1: String = /429963740182/vaults/test-vault-1

List all vaults in the region. A sequence of vault objects is returned, in this case it includes just the vault we created above. Please note that with vault operations the results are visible immediately.

scala> c.listVaults
res2: Seq[fi.markoa.glacier.Vault] = ArrayBuffer(Vault(arn:aws:glacier:us-west-2:429963740182:vaults/test-vault-1,test-vault-1,2017-11-19T08:18:38.990Z,None,0,0))

Now we’re ready to upload an archive into the vault:

scala> c.uploadArchive("test-vault-1", "my backup archive", "my-backup.zip")

res3: fi.markoa.glacier.Archive = Archive(WREjqj2BItYhI5BGV7mdJGsDl3oztPvpvVh_hngm5SWqJkOd5jnLipLyYy2KkM74-3mkt85nUjI4a_hcQZhtLnQF03K0sv2Bc97BYEwYQ7M4O_lmtgrCTuGCyAEEiuQmCFfRSnBkTw,Some(my-backup.zip),0c5dc86251d157e29cfadb04ac615426600a4e1177a8ac2c1134d895378b3acd,10240000,Some(my backup archive))

Note that Glacier doesn’t maintain an up-to-date list vault contents - a list of contents needs to be requested explicitly and preparing it can take a very long time. For this reason Glacier client stores a local catalogue of archives per vault. Vault contents can be listed as follows:

scala> c.catListArchives("test-vault-1")
res4: Seq[fi.markoa.glacier.Archive] = ArraySeq(Archive(WREjqj2BItYhI5BGV7mdJGsDl3oztPvpvVh_hngm5SWqJkOd5jnLipLyYy2KkM74-3mkt85nUjI4a_hcQZhtLnQF03K0sv2Bc97BYEwYQ7M4O_lmtgrCTuGCyAEEiuQmCFfRSnBkTw,Some(my-backup.zip),0c5dc86251d157e29cfadb04ac615426600a4e1177a8ac2c1134d895378b3acd,10240000,Some(my backup archive)))

Archives need to be prepared prior to their retrieval and preparation can take several hours. For this reason it’s often more convenient to retrieve them asynchronously: 1) you request archive retrieval and after Glacier has finished preparing archive you can 2) download it.

scala> c.prepareArchiveRetrieval("test-vault-1", "WREjqj2BItYhI5BGV7mdJGsDl3oztPvpvVh_hngm5SWqJkOd5jnLipLyYy2KkM74-3mkt85nUjI4a_hcQZhtLnQF03K0sv2Bc97BYEwYQ7M4O_lmtgrCTuGCyAEEiuQmCFfRSnBkTw")
res1: Option[String] = Some(h479o4kxdawFsho0POzQAznw6e6beampFAIBYuI7s41O_HmzqqWsg2qk2vL2Lw_4MOsI1VFarvokz7NXczBq0CrwPKzv)

Archive retrieval is added in the vault’s list of jobs. You can list unfinished jobs as follows:

scala> c.listJobs("test-vault-1")
res4: Seq[fi.markoa.glacier.Job] = ArrayBuffer(Job(h479o4kxdawFsho0POzQAznw6e6beampFAIBYuI7s41O_HmzqqWsg2qk2vL2Lw_4MOsI1VFarvokz7NXczBq0CrwPKzv,arn:aws:glacier:us-west-2:429963740182:vaults/test-vault-1,ArchiveRetrieval,null,2017-11-19T09:00:34.339Z,InProgress,null,None,Some(WREjqj2BItYhI5BGV7mdJGsDl3oztPvpvVh_hngm5SWqJkOd5jnLipLyYy2KkM74-3mkt85nUjI4a_hcQZhtLnQF03K0sv2Bc97BYEwYQ7M4O_lmtgrCTuGCyAEEiuQmCFfRSnBkTw)))

Notice the InProgress status. Once archive preparation has been finished the job list will look something like this:

scala> c.listJobs("test-vault-1")
res8: Seq[fi.markoa.glacier.Job] = ArrayBuffer(Job(h479o4kxdawFsho0POzQAznw6e6beampFAIBYuI7s41O_HmzqqWsg2qk2vL2Lw_4MOsI1VFarvokz7NXczBq0CrwPKzv,arn:aws:glacier:us-west-2:429963740182:vaults/test-vault-1,ArchiveRetrieval,null,2017-11-19T09:00:34.339Z,Succeeded,Succeeded,Some(2017-11-19T12:52:38.363Z),Some(WREjqj2BItYhI5BGV7mdJGsDl3oztPvpvVh_hngm5SWqJkOd5jnLipLyYy2KkM74-3mkt85nUjI4a_hcQZhtLnQF03K0sv2Bc97BYEwYQ7M4O_lmtgrCTuGCyAEEiuQmCFfRSnBkTw)))

Setting up notifications relieves you from having to periodically poll job completion status and instead receive notifications. Notifications can be set up via AWS Console.

A prepared archive can then be downloaded from Glacier using the retrieval job ID:

scala> c.downloadPreparedArchive("test-vault-1", "h479o4kxdawFsho0POzQAznw6e6beampFAIBYuI7s41O_HmzqqWsg2qk2vL2Lw_4MOsI1VFarvokz7NXczBq0CrwPKzv", "my-backup-restored.zip")

That’s it for the basic operations!

Some other tasks Glacier client lets you do include delete vault, request a vault inventories (list of archives a vault contains), download inventories and delete archives.
