Dump Restore

DEPRICATED AS ON 12 APRIL 2017 - katkamrachana Merging of 2 different instance’s data.

How to Restore ?

• Suppose we have backup of 2 schools/servers say S1 ad S2.
• S1 /data having:
  • db
  • rcs-repo
  • media
• S2 /data having:
  • db
  • rcs-repo
  • media

Step 1: On a clean /data, copy S1’s /data.

Step 2: Run “python manage.py data_dump” This will create ‘gstudio:sub:datarestore’ under /data that will contain the RCS files.

Step 3: Take dump of Benchmarks collection. (Since we do not have RCS of this collection) Run “mongodump –db <db:sub:name> –collection Benchmarks data/gstudio:sub:`datarestore`/Benchmarks:sub:`dump`” This will create a Benchmarks.bson file.

Step 4: On a clean /data, copy S2’s /data.

Step 5: Go to shell: python manage.py shell

Step 6: execfile(‘../doc/deployer/restore_dump.py’) This file takes rcs dump created in step 2. Paths defined: nodes_path = ‘/data/gstudio:sub:datarestore/data/rcs-repo/Nodes’ triples_path = ‘/data/gstudio:sub:datarestore/data/rcs-repo/Triples’ filehives_path = ‘/data/gstudio:sub:datarestore/data/rcs-repo/Filehives’ Modify these paths, if you have moved the Step 2 output location.

Step 7: Restore Benchmarks collection dump of Step 3. Run: mongorestore –db meta-mongodb –collection /data/gstudio:sub:datarestore/Benchmarks:sub:dump/Benchmarks.bson

Step 8: Run fix_nodes.py. This script resets data-type of all the datetime related values from long to datetime object

Note: S1 and S2 should be updated with alpha branch (Filehive implementation)
