I take it this script would run automatically at intervals. Given that, I think you could make your approach work. I'd break the archiving and deleting into two steps, so you can bail in case of error before files are trashed, rather than after.

Also, Once a tarball is created and compressed, it's essentially uneditable, so you have to compress it after you're finished appending to it, not during.



Code:
# Logfile for errors, >&2 and any errors printed by tar/gzip/etc
exec 2> /path/to/errorlog
# Logfile for files, captures default stdout
exec 1> /path/to/filelog

TSTAMP=$(date +%Y-%m-%d)
TARBALL=/path/to/folder/$TSTAMP-one.tar

echo "$(date '+%Y-%m-%d %H:%M:%S') $0 Beginning execution" >&2

echo "# Archiving to $TARBALL"

if [ -e "$TARBALL" ] || [ -e "$TARBALL".gz ]
then
        echo "$(date '+%Y-%m-%d %H:%M:%S') $TARBALL already exists, refusing to overwrite" >&2
        exit 1
fi

tar -rf "$TARBALL" # Create empty tar file to append to

if ! find one -type f -exec echo ls -latr '{}' '+' -exec echo tar -rvf /absolute/path/to/archive.tar '{}' '+'
then
        echo "$(date '+%Y-%m-%d %H:%M:%S') Creating archive failed" >&2
        rm -f "$TARBALL"
        exit 1
fi

if ! gzip "$TARBALL"
then
        echo "$(date '+%Y-%m-%d %H:%M:%S') Couldn't compress $TARBALL" >&2
        exit 1
fi

if ! find one -type f -exec echo rm '{}' '+'
then
        echo "$(date '+%Y-%m-%d %H:%M:%S') Error removing files" >&2
        exit 1
fi

echo "$(date '+%Y-%m-%d %H:%M:%S') $0 completed successfully"

doveadm-log

DOVEADM-LOG(1)							      Dovecot							    DOVEADM-LOG(1)

NAME

       doveadm-log - Locate, test or reopen Dovecot's log files

SYNOPSIS

       doveadm [-Dv] log errors [-s min_timestamp]
       doveadm [-Dv] log find [directory]
       doveadm [-Dv] log reopen
       doveadm [-Dv] log test

DESCRIPTION

       The  doveadm  log commands are used to locate and reopen the log files of dovecot(1).  It's also possible to test the configured targets of
       the *log_path settings.

OPTIONS

       Global doveadm(1) options:

       -D     Enables verbosity and debug messages.

       -v     Enables verbosity, including progress counter.

COMMANDS

   log errors
       doveadm log errors [-s min_timestamp]

       The log errors command is used to show the last	- up to 1,000 - errors and warnings.  If no output is generated, no errors  have  occurred
       since the last start.

       -s min_timestamp
	      An  integer  value, representing seconds since the epoch - also known as Unix timestamp.	When a min_timestamp was given, doveadm(1)
	      will only show errors occurred since that point in time.

   log find
       doveadm log find [directory]

       The log find command is used to show the location of the log files, to which dovecot(1) sends its log messages.	 If  dovecot(1)  logs  its
       messages  through  syslogd(8)  and doveadm(1) could not find any log files, you can specify the directory where your syslogd writes its log
       files.

   log reopen
       doveadm log reopen

       This command causes doveadm to reopen all log files, configured in the log_path, info_log_path and debug_log_path settings.  These settings
       are configured in /etc/dovecot/conf.d/10-logging.conf.
       This is for example useful after manually rotating the log files.

   log test
       doveadm log test

       This command causes doveadm to write the message "This is Dovecot's priority log (timestamp)" to the configured log files.  The used prior-
       ities are: debug, info, warning, error and fatal.

EXAMPLE

       This example shows how to locate the log files used by dovecot(1).

       doveadm log find
       Looking for log files from /var/log
       Debug: /var/log/dovecot.debug
       Info: /var/log/mail.log
       Warning: /var/log/mail.log
       Error: /var/log/mail.log
       Fatal: /var/log/mail.log

       Report bugs, including doveconf -n output, to the Dovecot Mailing List <dovecot@dovecot.org>.  Information about reporting bugs	is  avail-
       able at: http://dovecot.org/bugreport.html
