Avamar Administrator technical notes
The following technical notes apply to Avamar Administrator.
Avamar Administrator directory browsing limitation
When browsing a client file system with Avamar Administrator, directories with very large
numbers of files can cause Avamar Administrator to run out of memory. For this reason,
Avamar Administrator is configured by default to only retrieve the first 50,000 files in each
directory. You can change this limitation by editing the max_browse_entries settings
in mcserver.xml and mcclient.xml. However, doing so could cause unpredictable
application behavior.
Schedule start times and end times
If you select a different start time in the schedule, you must reselect the desired end time.
Additional “cold start” messages from netsnmp
To resolve an issue where SNMP stops responding, Avamar must frequently restart the
netsnmp agent. Because the netsnmp agent generates a “cold start” message on each
restart, additional “cold start” messages appear that are not related to actual restarts of
the Avamar system or incorrect operation of the system. Unfortunately, there is currently
no way to distinguish between a real “cold start” message that is triggered by an Avamar
system restart and a “cold start” message generated as the result of netsnmp agent
restarts.
Software conflicts with Black Ice and Timbuktu
The Avamar Administrator software is known to have conflicts with software packages
such as Black Ice and Timbuktu.
Backup client technical notes
The following technical notes apply to backup clients.
Linux client installation binaries
Because various Linux operating systems are compatible, not all supported Linux
operating systems have natively-built installation binaries. As a result, the names of
installation binaries do not always match the name of the operating system. For example,
client installation binaries for Red Hat Enterprise Linux 6 are built on SUSE Enterprise
Server 11 and therefore refer to SLES 11 in the name of the installation binaries.
Nonetheless these installation binaries are appropriate for installation on Red Hat
Enterprise Linux 6.
IPv6 not supported on HP-UX PA-RISC
Avamar support for IPv6 is not available for the HP-UX PA-RISC platform.
