Cannot use filesystem while sending a snapshot
I've got a Solaris 11 Express installed on my machine. I have created a raidz2 zpool named shares and a simple one-disc zpool named backup. I have made a script that would send a daily snapshot of shares to backup.
I use these commands
zfs snapshot shares@DDMMRRRRHHMM
zfs send -i shares@.... shares@DDMMRRRRHHMM | zfs receive -F backup
It works quite fine, but for one important issue. If i make a change to the shares filesystem while sending the snapshot, the snapshot is not send properly.
I currently unmount the filesystem before and mount it back again after the transfer completes, but that is unfortunatelly an unacceptable situation.
Thanks in advance for all replys,
Dusan

Hi guys!
Could you tell me what's the difference of filesystem of Solaris to filesystem of Windows? I need to compare both.
I have read some over the net but it's so much technical. Could you explain it in a more simpler term? I am new to Solaris. Hope you help me guys.

NAME
amanda-applications - Application-api for amanda
DESCRIPTION
Describe how to use application with Amanda
APPLICATIONS
This section lists the applications included with Amanda. See the individual man pages for instructions on using them. For complete How-To
information, consult the Amanda wiki at http://wiki.zmanda.com.
o amgtar(8), - use GNU Tar to backup and restore data.
o ampgsql(8), - use PostgreSQL's continuous WAL archiving.
o amraw(8), - use open and read to read the data.
o amsamba(8), - use smbclient to backup and restore data.
o amstar(8), - use star to backup and restore data.
o amsuntar(8), - use native tar on Solaris to backup and restore data.
o amzfs-sendrecv(8), - use zfs to create a snapshot and use 'zfs send' to generate the backup.
o amzfs-snapshot(8), - use zfs to create a snapshot and for use with other applications (e.g. amgtar)
DEFINING APPLICATIONS
An application is defined in amanda.conf(5) as follows:
define application-tool $appconfigname {
plugin "$pluginname"
property "$PROPERTY_NAME" "$PROPERTY_VALUE"
...
}
and then referenced in a dumptype as
define dumptype $dumptypename {
...
program "APPLICATION"
application "$appconfigname"
}
Application properties, like Amanda configuration parameters, are insensitive to case, and - (dash) and _ (underscore) may be used
interchangeably.
See the individual plugin documentation for properties applicable to each plugin.
