I've tried using the backup and restore script in

/usr/lib/perfsonar/scripts

with limited success. Here are a few things:

1) If you do a backup (with data "-d") of a clean system (no tests configured) you get an error

root@oit-82-33 cassandra]# /usr/lib/perfsonar/scripts/ps-toolkit-migrate-backup.sh -d ~petry/backuptest

Backing-up users...[SUCCESS]

Backing-up groups...[SUCCESS]

Backing-up passwords...[SUCCESS]

Backing up administrative users...[SUCCESS]

Backing-up toolkit configuration...[SUCCESS]

Backing-up bwctl-server configuration...[SUCCESS]

Backing-up owamp-server configuration...[SUCCESS]

Backing-up pScheduler configuration...[SUCCESS]

Backing-up NTP configuration...[SUCCESS]

Backing-up cassandra data...Unable to snapshot cassandra database

Digging into the bash script, it fails on doing the node tool command.

Its a corner case, but annoying. (Once there is data, there is another problem see 2.)

Notetool on clean system

---------------------------------

nodetool snapshot esmond -t esmond_snapshot

Requested creating snapshot for: esmond

Exception in thread "main" java.io.IOException: Keyspace esmond does not exist

at org.apache.cassandra.service.StorageService.getValidKeyspace(StorageService.java:2298)

2) do the same backup on a system with data. Do it a second time and you'll get.

the script should probably clean up after itself and do a "nodetool clearsnapshot"

[root@ps-10g-sdmz scripts]# /usr/lib/perfsonar/scripts/ps-toolkit-migrate-backup.sh -d ~petry/backuptest
