[samidha]

Manage disk space on SafeSquid server. When any of the partitions that are used by SafeSquid are full, it results in undefined behavior.
This may lead to something like, SafeSquid failing in processing the connections.

Give the enough size to backup store.
Example : If you want to take a backup of files of size 5GB then consider the store upto 5.5 GB
Don't delete the original log files (.log extension) and database files.
Run below command to check available disk space on each partition.
df -kh
