Dear ARL DSRC User,

Effective October 1, 2019, user $HOME directory backups will be limited to 1TB of data. ARL DSRC is modifying the local implementation of the Baseline Configuration Team (BCT) policy where user data from their $HOME file system will be backed up on a weekly basis. Users exceeding 1TB of data on $HOME will not be backed up for each week data is in excess of 1TB.

To view $HOME data amount, use the following command: "/app/unsupported/BC/show_home"

--------------------  EXAMPLE: --------------------
excalibur11:~> show_home 
/p/home/philm contains 140 Gb of data 
excalibur11:~>
---------------------------------------------------

This policy implementation is a result of excessive data in $HOME file systems, hindering the completion of the backup process.
