/* /*
* This is a second implemetation of a shadow copy module for exposing
This is a 3rd implemetation of a shadow copy module for exposing * file system snapshots to windows clients as shadow copies.
snapshots to windows clients as shadow copies. This version has the *
following features: * See the manual page for documentation.
1) you don't need to populate your shares with symlinks to the
snapshots. This can be very important when you have thousands of
shares, or use [homes]
2) the inode number of the files is altered so it is different
from the original. This allows the 'restore' button to work
without a sharing violation
3) shadow copy results can be sorted before being sent to the
client. This is beneficial for filesystems that don't read
directories alphabetically (the default unix).
4) vanity naming for snapshots. Snapshots can be named in any
format compatible with str[fp]time conversions.
5) time stamps in snapshot names can be represented in localtime
rather than UTC.
Module options:
shadow:snapdir = <directory where snapshots are kept>
This is the directory containing the @GMT-* snapshot directories. If it is an absolute
path it is used as-is. If it is a relative path, then it is taken relative to the mount
point of the filesystem that the root of this share is on
shadow:basedir = <base directory that snapshots are from>
This is an optional parameter that specifies the directory that
the snapshots are relative to. It defaults to the filesystem
mount point
shadow:fixinodes = yes/no
If you enable shadow:fixinodes then this module will modify the
apparent inode number of files in the snapshot directories using
a hash of the files path. This is needed for snapshot systems
where the snapshots have the same device:inode number as the
original files (such as happens with GPFS snapshots). If you
don't set this option then the 'restore' button in the shadow
copy UI will fail with a sharing violation.
shadow:sort = asc/desc, or not specified for unsorted (default)
This is an optional parameter that specifies that the shadow
copy directories should be sorted before sending them to the
client. This can be beneficial as unix filesystems are usually
not listed alphabetically sorted. If enabled, you typically
want to specify descending order.
shadow:format = <format specification for snapshot names>
This is an optional parameter that specifies the format
specification for the naming of snapshots. The format must
be compatible with the conversion specifications recognized
by str[fp]time. The default value is "@GMT-%Y.%m.%d-%H.%M.%S".
shadow:sscanf = yes/no (default is no)
The time is the unsigned long integer (%lu) in the format string
rather than a time strptime() can parse. The result must be a unix time_t
time.
shadow:localtime = yes/no (default is no)
This is an optional parameter that indicates whether the
snapshot names are in UTC/GMT or the local time.
The following command would generate a correctly formatted directory name
for use with the default parameters:
date -u +@GMT-%Y.%m.%d-%H.%M.%S
