.SH "NAME"
vfs_worm \- disallows writes for older file
.SH "SYNOPSIS"
.HP \w'\ 'u
vfs objects = worm
.SH "DESCRIPTION"
.PP
This VFS module is part of the
\fBsamba\fR(7)
suite\&.
.PP
The
vfs_worm
module controls the writability of files and folders depending on their change time and a adjustable grace period\&.
.PP
If the change time of a file or directory is older than the specified grace period, the write access will be denied, independent of further access controls (e\&.g\&. by the filesystem)\&.
.PP
In the case that the grace period is not exceed, the worm module will not impact any access controls\&.
.SH "OPTIONS"
.PP
worm:grace_period = SECONDS
.RS 4
Period in seconds which defines the time how long the write access should be handled by the normal access controls\&. After this grace period the file or directory becomes read only\&.
.RE
.SH "EXAMPLES"
.PP
Deny the write access to files and folders, which are older than five minutes (300 seconds):
.sp
.if n \{\
.RS 4
.\}
.nf
\fI[wormshare]\fR
\m[blue]\fBvfs objects = worm\fR\m[]
\m[blue]\fBworm:grace_period = 300\fR\m[]
.fi
.if n \{\
.RE
.\}
.SH "VERSION"
.PP
This man page is part of version 4\&.20\&.1 of the Samba suite\&.
.SH "AUTHOR"
.PP
The original Samba software and related utilities were created by Andrew Tridgell\&. Samba is now developed by the Samba Team as an Open Source project similar to the way the Linux kernel is developed\&.
