# Data Archiving and Reloading

# I. Data archiving function (ta_data_archive)

The data archiving function is to migrate and archive some historical data or data that does not need to be used for the time being to cheap storage, so as to release the disk resources of the TA cluster and save the use cost.

# 1.1 Archiving commands

#start
ta-tool data_archive start

#stop
ta-tool data_archive stop

#retry
ta-tool data_archive retry -jobid *******

# 1.2 Archiving method

# 1.2.1 S3 method

# 1.2.1.1 Environmental preparation

  1. Apply for Amazon S3 service
  2. Create a bucket (Bucket) for archiving, and the area of the bucket is recommended to be consistent with the TA cluster server
  3. Create the key to access the bucket

# 1.2.1.2 Sample commands

[ta@ta1 ~]$ ta-tool data_archive start
Please enter JobId for this job without background random generation>
------------------------------------------------------------
Please enter the project appid that needs to be archived> 5487f6b**********f9c379aa9bb
------------------------------------------------------------
Please enter the start time for project archiving: YYYY-MM-DD > 2018-01-01
------------------------------------------------------------
Please enter the end time for project archiving: YYYY-MM-DD > 2018-12-31
------------------------------------------------------------
Please enter the event type for project archiving (not required)>
------------------------------------------------------------
Please enter the type of archive storage: hdfs or rsync or s3 > s3
------------------------------------------------------------
Please enter S3 AccesskeyID> AK************YO6G3
------------------------------------------------------------
Please enter S3 secretAccessKey> J23************rZb
------------------------------------------------------------
Please enter S3 region code> cn-****-1
------------------------------------------------------------
Please enter S3 bucket name>ta************ive
------------------------------------------------------------
Please enter the S3 file storage class (default: STANDARD)> S*****D
------------------------------------------------------------
Please enter the target directory for project archiving>  data*****_test
------------------------------------------------------------

# 1.2.1.3 Step description

  1. Enter jobid, which can be customized or generated in the background. Specify jobid when the task fails and retries.
  2. Enter project appid
  3. Enter the start date (outside the most recent month)
  4. Enter the end date (outside the most recent month)
  5. Enter the specified event type (not required) to archive a single event type
  6. Select the type of archival storage S3
  7. Enter the accesskeyid for s3
  8. Enter the secretAccessKey (managed in the S3 IAM service)
  9. Specify bucket (opens new window) region code
  10. Enter bucket name
  11. Select the storage type (opens new window) (standard mode by default). The GLACIER and DEEP_ARCHIVE storage classes in the storage type are designed for low-cost data archiving, but they require thawing operations during data recovery. It is more cumbersome.
  12. The archived target directory (the directory will be created under the target bucket, and the archived data will be placed in the directory)

# 1.2.3 rsync method

# 1.2.3.1 Environmental preparation
  1. Use rsync daemon mode to set up the server, and copy the secret key file to the command running node in the TA cluster
# 1.2.3.2 Sample commands
[ta@ta1 ~]$ ta-tool data_archive start

# II. Data reloading function (ta_data_reload)
